Founder Diaries · When You Are Tired of Buying It Again
By Sonal Sahani · ISIPCA Versailles 16 min read Updated October 2026
The money question in this subject has been asked the wrong way round for as long as I have been answering it. Readers want a total, and a total is the least interesting thing their purchase record contains. What their record actually holds, and what no total can show, is a count: the number of fragrances they threw away with oil still in them. Each one of those was a product bought twice. Not a product that was too expensive, not a product that failed - a product that was replaced early, by a buyer who had stopped being able to tell. That count is the money finding, it is yours to make rather than mine to supply, and it takes about four minutes.
Quick answers — read this first
Could getting used to a scent be making me waste money on car fragrance? Yes, and the waste shows up as a count rather than a sum. Go through the fragrances you bought this year and mark each one as emptied or abandoned. Abandoned means you replaced it while there was still liquid in the bottle. Every item in that column was bought twice, because the oil you were replacing was still in the car. Readers with this symptom usually find the abandoned column is the longer one, which is a different problem from spending too much.

Is the answer to buy a reusable system instead? Only if your complaint is about the throwing away or about control of release. A device does not stop a nose settling on a constant smell, and it will not make you a better judge of your own cabin - SOSA Safar at ₹3,999 is honest about that. What a high abandoned-count actually points at is rotation and a free test, neither of which is hardware.

What does the count tell me that an annual total does not? Which half of your spending bought you something. A total treats every purchase as equivalent; the count separates the ones that replaced an empty bottle from the ones that replaced a working product. Those two groups have completely different remedies, and the full year-cost working has its own page, linked below, so this one does not repeat it.
The short answer
Short answer: Make the count before you make any decision, because it is the only figure in this subject that is both free and yours. What to count - every car fragrance you bought in the last twelve months, sorted into two columns, emptied and abandoned. What counts as abandoned - you replaced it while liquid was still visible, or while a spray still produced mist. Not nearly empty. Not stopped smelling. What a high abandoned column means - you have been buying duplicates of oil already in your car, and the cause is that you stopped being able to detect a smell you meet every day. What it does not mean - that you spend too much, which is a separate question with its own page. What the remedy is - rotation and a free test, not a bigger purchase.
The pick: a count of zero means you empty what you buy, and the only correction is price: 15ml hanging refills at ₹399 to ₹449 rather than rebuying the 12ml unit at ₹449 to ₹509. A high count means stop buying until a passenger has smelled your cabin, then rotate rather than replace - the drawer first at ₹0, a discovery set at ₹699 to ₹899 when the drawer is empty. SOSA Safar at ₹3,999 or ₹4,499 is for control of release, not for the count.
Next step: do the count tonight on the back of an envelope, then read the page that explains why you stopped detecting them, which is the cause behind every entry in your abandoned column. The mark-the-level reading stops the column growing next year. Or send me your two columns and I will tell you which of them is the problem.
In this guide
Straight answer
Could olfactory adaptation be making me spend unnecessary money constantly trying new car fragrances?
Very probably, and the way to find out is a count rather than a calculation. I want to be careful here, because this is a money question and money questions in this category are where pages go wrong - they produce a total, the total looks alarming, and the alarm is then used to sell hardware. I am not going to do that. The full year-cost working exists on its own page in a neighbouring cluster, it is linked below, and it carries the arithmetic properly. What this page contributes is something that working never isolated. Take the fragrances you bought in the last twelve months and sort them into two columns. Column one: the ones you threw away empty. Dry bottle, no mist from the spray, nothing left. Column two: the ones you replaced while there was still liquid in them. That second column is the only part of your spending that is genuinely in question, and most readers have never looked at it, because a purchase record is usually remembered as one undifferentiated stream of small, forgettable payments. Here is why the second column is the interesting one. A product you emptied did its job. You bought fragrance, you received fragrance until the fragrance ran out, and the transaction completed. The only improvement available to you is to buy the same oil for less money, which for a hanging format means a 15ml refill at ₹399 to ₹449 rather than another 12ml unit at ₹449 to ₹509 - less money and a larger bottle. That is a price correction, not a diagnosis. A product you abandoned is a different animal entirely. You paid for oil, received some of it, and then bought more oil while the first lot was still in the car. If you had three of those this year, you did not buy three products - you bought one and a half, twice. And since the thing in the bin still worked, the question becomes: what made you decide it had stopped? The answer, for the overwhelming majority of readers who ask me this, is that they stopped being able to detect it. A nose stops reporting a smell that never changes, and the person worst affected is the one sitting nearest the source for the longest - which, in your car, is you. The mechanism has its own page in this family and I am not going to re-explain it here. What matters for a money page is the consequence: that effect does not make you buy a more expensive product, it makes you buy a product sooner, and sooner is where the money goes. This is why I rank it above the other reasons readers keep buying car fragrance. A reader who dislikes the format wastes money on the wrong kind of thing, which is at least a visible mistake. A reader who has never worked out which scent they like wastes money on guesses, which at least produces information eventually. A reader in your position buys an exact duplicate of something that is already working, repeatedly, and every single purchase feels justified at the time. And the count is better than a total for a reason that goes beyond diagnosis: it is honest in a way a total cannot be. A total needs you to remember what you paid, which you will get wrong, and then has to be set against the cost of an alternative that nobody can complete, because consumption is not published for any format by SOSA or anyone else. A count needs you to remember only whether a bottle was empty. That is a visual memory rather than a financial one, and visual memories about your own car are far more reliable than your recollection of what you spent in April. So: two columns, four minutes, tonight. If the abandoned column is short or empty, you are a straightforward consumer of fragrance and nothing on this page applies to you beyond a price correction. If it is long, you now know something specific about where your money went, and the remedy is not a bigger purchase.
Where the working already lives
Separating consumption that comes from genuinely driving a lot from consumption that comes from applying more than you need, and the long-run cost of a habit that feels inexpensive every single time, are both written out in full on the two pages linked below. They hold the arithmetic and the years. I am not going to rebuild any of it here, because this page is not about what the habit totals. It is about which of your purchases bought you something you already owned.
How Can I Distinguish High Fragrance Consumption Caused by Frequent Driving From Consumption Caused by Repeated Unnecessary Application?
If I Keep Buying Car Perfume Because Each Purchase Feels Inexpensive, How Can I Calculate What the Habit Actually Costs Over Several Years?

Why a total hides exactly the thing you need to see

A twelve-month total is a single number laid over twelve different decisions, and the averaging is what destroys the information. Two readers can arrive at an identical annual figure and be in completely opposite situations: one emptied everything they bought and simply drives a great deal, the other abandoned most of what they bought and drives normally. The first has a price problem. The second has a perception problem. A total cannot tell them apart and a count does it immediately.

Two readers, the same year's spending, nothing else in common
The purchase that completed, and the purchase that bought a duplicate
The product really is finished You have stopped registering it
The emptied column. Fragrance bought, fragrance received, bottle dry, transaction finished. Nothing here needs diagnosing and nothing here is waste, however large the column is - a long emptied column just means you use a lot, which is a usage fact rather than a fault. The only move available is to buy the identical oil for less money, and for a hanging format that is a 15ml refill at ₹399 to ₹449 against ₹449 to ₹509 for a fresh 12ml unit, in a larger bottle than the one it refills. The abandoned column. Fragrance bought, some of it received, and then replaced while the rest of it was still in the car. Every entry here is a product bought twice. The decision that created each entry was made by a nose that had settled on the smell, which means the evidence it rested on was unreliable in a predictable direction - always towards "it has stopped", never towards "it is fine". Nothing you buy addresses this column. It shrinks only when the decision method changes.
The test that tells them apart, and it is free: Sort them, do not add them. One line per purchase, the scent or the format on the left and a single word on the right: emptied or abandoned. If you cannot remember which, that entry goes in the abandoned column, because a bottle you binned dry is a thing you would remember doing. The whole exercise fits on an envelope and it is the only part of this subject where new information enters.
I will not supply a threshold at which the abandoned column becomes a problem, because any figure I named would be invented. What I will say is that readers who write to me describing a fragrance that goes quiet after a few weeks almost always find the abandoned column is the longer of the two, and that finding alone usually changes what they do next more than a year's total ever has.
1
The reason this is the most expensive of the four causes
Nothing about it feels wasteful in the moment, so nothing stops it
Consider what the other causes feel like from inside. A reader who hates spraying feels irritated every time they spray, and irritation eventually prompts a change. A reader guessing at scents feels disappointed on opening each one, and disappointment is at least informative. A reader fighting a damp cabin notices the smell coming back, which is a clue. The reader in the abandoned column feels none of that. Each purchase is a small, pleasant, entirely rational-seeming act: the car stopped smelling of anything, so you bought something that made it smell of something. The feedback loop that would correct the behaviour never closes, because the new product does work, briefly, exactly as predicted.
The sentence to listen for in your own head: “this one didn't last either”. If you have thought that about three or more different products, the thing that did not last is unlikely to be the products.
2
Why the count is a better instrument than your bank statement
A statement records what you paid; the count records what you received
I get sent bank statements by readers trying to settle this, and they are almost useless, because a payment tells you nothing about whether the thing you bought was consumed. The count does. And it has a second advantage: it is robust against the thing that makes money recollection unreliable here, which is that each purchase is small enough to forget by the following week. You will not reliably remember paying for the one you bought in March. You will remember whether the bottle you took out of the car in March was empty, because that is a picture rather than a figure. If you kept no record at all, the page on reconstructing twelve months of buying shows how to recover one.
What a long abandoned column actually points at. Not a bigger purchase - something to alternate with, so the cabin presents a difference rather than a constant. Start with whatever half-used bottles are already in the drawer, at ₹0. A discovery set of three is ₹699 to ₹899, and the pack of nine is ₹2,999, for when the drawer is empty.
See the discovery sets →
The money finding here is a count, not a total. Sort every car fragrance you bought in the last twelve months into two columns: emptied, and abandoned while there was still liquid in it. The emptied column is not waste at any size and its only correction is price - a 15ml refill at ₹399 to ₹449 rather than a 12ml unit at ₹449 to ₹509. Every entry in the abandoned column is a product bought twice, and the decision that created it was made by a nose that had settled on the smell. That column does not shrink by buying something better; it shrinks when the decision method changes to a passenger and a look at the bottle.
If every product you replaced this year was visibly empty when you replaced it, this page has nothing to tell you and the money was not wasted whatever your perception was doing. An abandoned column of zero means your buying is tracking consumption rather than detection, and the fact that the cabin went quiet before the bottle ran dry is then a longevity question rather than a waste question. In that case the only correction worth making is the price of the same oil, your annual figure means what it appears to mean, and you should spend your attention on the sibling page that does the arithmetic rather than on this one.
— the condition that reverses this page
The line nobody can fill in for you
There is one thing the count cannot do, and I want to be straight about it: it cannot tell you how much oil was left in the bottles you abandoned, so it cannot be turned into a rupee figure. Nobody publishes a consumption rate for a 12ml car perfume in either format, for the 20ml bottle supplied with the device or for any speed setting, and no such figure exists for your cabin and your month. So the count stays a count. If you want to stop the column growing, mark the liquid level on your current bottle, write the date beside the mark, and look again in a fortnight.
If your abandoned column is empty, the only correction you need is price: a 15ml hanging refill is ₹399 to ₹449 against ₹449 to ₹509 for rebuying the 12ml unit, in a larger bottle.
See the 15ml hanging refills → Ask SOSA to run your numbers

Making the count honestly, which is harder than it sounds

The count only works if you are strict about one word, and the word is abandoned. A bottle that was nearly empty is not empty. A bottle that had stopped smelling is not empty. A bottle you assume must have been empty because you would surely not have replaced a working one is the entry this whole exercise exists to catch, and it belongs in the abandoned column by default.

Work from physical memory rather than from feeling. For each purchase, try to picture the moment of disposal: the unit coming off the mirror, the bottle going into the bin, whether you could see liquid moving in it. If no picture comes, mark it abandoned, because the disposal of a genuinely dry bottle is a small satisfying event that tends to stick. If you still have any of them in a drawer, go and look - half-used bottles in a drawer are the physical evidence for this count and most readers with this symptom have several.

Then stop. Do not price the columns, do not multiply anything, and do not try to work out what fraction of each abandoned bottle was left. Those are the moves that turn a reliable count into an unreliable sum, and the sum needs a consumption figure that does not exist. The count by itself is enough to change what you do next, which is all a diagnosis has to do.

What each column size makes you do

Three outcomes, and the one that matches you is decided by the shape of your two columns rather than by what you spent. Read the row whose description you recognise rather than the one whose price suits you.

There is a fourth shape and it is not in the table because it costs ₹0: an abandoned column that is long and a reader who has not yet asked a single passenger whether the cabin smells of anything. That reader should spend nothing until the test has run, because the whole count rests on a decision method that has not been corrected. Device refills are ₹1,049 per 100 gm and ₹1,849 per 300 gm for the SOSA scents and ₹1,099 and ₹1,899 for the hotel-inspired ones; those are weights while the car perfumes are volumes, so the two systems cannot be put on one per-millilitre footing from the published figures.
Sonal’s recommendation
Make the count tonight, and let the shorter column decide what I am allowed to sell you
I have been asked for an annual total on this subject hundreds of times and I have never once seen it change what somebody did. The count changes it almost every time, and the count costs nothing and comes from your own bin rather than from me.
— Sonal Sahani, founder and perfumer, ISIPCA Versailles-trained
What to do tonight, at ₹0 One line per car fragrance you bought this year, with one word beside it: emptied or abandoned. If you cannot picture a dry bottle, write abandoned.
What to do with the drawer Go and look in it. Half-used bottles are the physical evidence for this count, and they are also your free rotation stock.
What to buy if nothing was abandoned The 15ml hanging refill in your existing scent at ₹399 to ₹449, rather than rebuying the 12ml unit at ₹449 to ₹509.
What to buy if most were abandoned Nothing, until a passenger has told you whether your current one still smells. Then rotate, starting from the drawer.
What not to do with the count Price it. Turning a count into a sum needs a consumption figure that nobody publishes, and the count is more useful without one.
I point readers at the refill first because it is the only correction that is unambiguously right for the group it belongs to, and because it is less money than the thing they were about to buy. For the group with the long abandoned column, the honest recommendation is that there is nothing for me to sell this month: the purchases were duplicates and another purchase is another duplicate until the decision method changes. SOSA Safar at ₹3,999 belongs to the reader who wants the disposal and the release under their own control, and I would rather they bought it for that reason than in the belief that it shortens the abandoned column, because it does not. Check the scent against the waterless range before the price.

“Most of them still had liquid in them.” Then those purchases were duplicates and the next one will be too, unless something other than the product changes.

A note from Sonal

I built this page around a count rather than a total because the totals I have produced for readers over the years have been strangely ineffective. People read them, agree that the figure is larger than they thought, and carry on exactly as before. The count does something a total does not: it tells you that a specific number of specific purchases bought you nothing, and that is a much harder thing to put down.

My own version of this was a drawer with four half-used bottles in it, and the detail I remember is that I knew the drawer existed while I was buying the fifth. I had not decided the four were useless. I had simply stopped experiencing them, which felt the same as them being gone, and the drawer was the evidence that it was not the same at all.

So go and look in your drawer before you order anything, and write the two columns out. If the abandoned column is long, the most useful thing I can sell you this month is nothing - read the page that explains why you stopped detecting them and the page that puts rotation against escalation, which starts with the bottles you already own at ₹0. Or send me the two columns and I will tell you which of them is actually your problem.

Frequently asked questions

How can I tell whether getting used to a scent has been costing me money?
Count rather than total. Sort every car fragrance you bought in the last twelve months into two columns: the ones you threw away empty, and the ones you replaced while there was still liquid in them. The second column is the money finding. Every entry in it is a product you bought twice, because the oil you were replacing was still in the car when the replacement arrived.
What counts as a product I abandoned rather than finished?
Any one you replaced while liquid was still visible in the bottle, or while a spray still produced mist when pressed. Nearly empty does not count as empty, and stopped smelling certainly does not. If you cannot picture the moment of disposal clearly enough to say whether the bottle was dry, put it in the abandoned column, because binning a genuinely empty bottle is a small event that tends to stick in the memory.
Why is a count more useful than working out what I spend a year?
Because a total averages twelve different decisions into one number and hides the only distinction that matters. Two readers with an identical annual figure can be in opposite positions: one empties everything they buy and simply drives a lot, the other abandons most of what they buy. The first has a price problem and the second has a perception problem, and the remedies have nothing in common.
Should I work out how much oil was left in the bottles I abandoned?
No, and it cannot be done honestly. Converting the count into a rupee figure needs a consumption rate for your format in your cabin, and no such figure is published by SOSA or by anybody else for a 12ml unit, the 20ml bottle supplied with the device or any speed setting. The count is more useful without a sum attached and it is the part you can actually trust.
Will buying a reusable device shorten the abandoned column?
Not by itself, and I would rather say so than imply otherwise. A device ends the disposal of units and gives you three speed settings and an auto shut-off, so it addresses control and waste of packaging. It does not change how a nose behaves towards a constant smell, which is what put the entries in that column in the first place. Rotation and a passenger's opinion do more for that column than hardware does.
The SOSA principle
A total tells you the size of your habit. A count tells you which half of it bought you something.
Which is why the arithmetic for this subject lives on its own page in a neighbouring cluster and this one does not repeat it. Purchase and refill prices are published; consumption is not, for any format, by anyone - so the honest contribution a page like this can make is a sorting exercise rather than a sum.

SOSA — The Count of Products You Bought Twice for a reader who suspects they have overspent and wants to know on what
Sort every car fragrance bought in the last twelve months into emptied and abandoned, where abandoned means replaced while liquid was still visible. The emptied column is not waste at any size and its only correction is price: 15ml hanging refills at ₹399 to ₹449 rather than rebuying the 12ml unit at ₹449 to ₹509, in a larger bottle. Every entry in the abandoned column is a product bought twice, created by a decision made with a nose that had settled on the smell. That column shrinks when the decision method changes, not when the product does. Rotation starts at ₹0 in your own drawer; discovery sets are ₹699 to ₹899 with a pack of nine at ₹2,999. SOSA Safar ₹3,999 or ₹4,499. No consumption figure is published, so the count is never converted into a sum.

About this guide: Written by Sonal Sahani, ISIPCA Versailles-trained founder and perfumer at SOSA Home & Body. The reasoning here - occupied cabin hours, evaporation while parked, airflow, exposure time and olfactory adaptation - applies to any brand; the products and prices are SOSA’s. Where SOSA publishes no figure, this guide says so and gives a way to measure it in your own vehicle rather than quoting a number.

Facts verified 7 October 2026 against the live SOSA product pages: SOSA car perfume is sold as one 12ml product in two formats at the SAME price, listed on the product page as "Spray (Strong scent-throw)" or "Hanging (Mild scent-throw)", with a "50 ML Car Perfume Spray" at ₹1,499. The nine scents are Jasmine ₹449, Lavender ₹479, Sandalwood ₹479, Icy Mint ₹489, Lemon ₹499, Vetiver khus ₹509, Sea Breeze ₹509, Oud ₹509 and Mysore Orange Blossom ₹549, the last of which is spray only. Car Hanging Freshener Refills are 15ml at ₹399 to ₹449 in eight scents - a larger bottle than the 12ml unit they refill. The SOSA Safar waterless car and travel diffuser is ₹3,999 for the SOSA scent trios and ₹4,499 for the hotel-inspired trios, with three speed settings, an auto shut-off timer at one, two or three hours, up to ten hours continuous or thirty hours intermittent per charge, a 2000 mAh battery, Type-C charging, a body of about 9 cm that fits a cup-holder, and a 20ml bottle in the box; it diffuses pure undiluted oil cold, with no water and no heat, and the product page states "Aroma only - does not humidify", which is not a claim that it dries a cabin or corrects damp. SOSA publishes NO coverage figure for Safar - no square feet, no cubic metres and no seat count - so no page here sizes it to a vehicle. Waterless Nebuliser Refills are shared with the SOSA Vaayu at ₹1,049 per 100 gm and ₹1,849 per 300 gm for the SOSA scents, and ₹1,099 and ₹1,899 for the hotel-inspired scents; that range contains no oud and no lavender, while the 12ml range contains both. The car perfumes are sold by volume and the waterless refills by weight, so a cost per millilitre across the two systems is not available from the published figures and none is given here. SOSA publishes no duration figure for a 12ml unit, a 20ml Safar bottle or any speed setting. No SOSA product removes an odour at its source: food, damp and smoke in a cabin are cleaning and ventilation problems, and fragrance sits on top of whatever is already there. SOSA makes no claim about mood, alertness, concentration, wellbeing or driving, and no claim about air quality or purification. After-sales terms, bulk arrangements and delivery commitments are confirmed with SOSA directly; free shipping above ₹499 is the only logistics fact stated. The hotel-inspired scent names are SOSA’s own interpretations and catalogue variant names; SOSA is independent and not affiliated with any hotel or brand named for reference. Prices and availability are subject to change - see the live product pages.
