Why are big refills over ₹1,000? Because they contain 300-500ml of oil - months of scent. Priced per ml they are the cheapest option; the sticker is higher only because you buy a lot at once.
What is the cheapest way to start? A 50ml SOSA reed diffuser from ₹749 gets you the vessel, reeds and oil; refill it big later for the best long-run value.

Quick answers — read this first
Is there a reed diffuser refill under ₹1,000? A large top-up refill (300ml/500ml) is ₹2,399-₹3,499, because it holds months of oil - but it works out to just ₹7-8 per ml, far cheaper than any small bottle under ₹1,000. The lowest-budget way into SOSA reeds is a full 50ml starter reed diffuser from ₹749, then refill later.Why are big refills over ₹1,000? Because they contain 300-500ml of oil - months of scent.

Straight answer
The honest answer: buy small to start, refill big to save
Here is the straight answer instead of a misleading one. A true large refill is not under ₹1,000 - a 300ml is ₹2,399 and a 500ml ₹3,499 - because each holds months of oil. But that is exactly why it is the cheapest option per ml at about ₹7-8, versus ₹15-17 for a little bottle. If your budget right now is under ₹1,000, the smart move is not a tiny cheap refill - it is a full 50ml SOSA reed diffuser from ₹749, which gets you the vessel, the reeds and the oil to start. Then, when it runs low, refill big and your cost per month of scent drops sharply. So the honest under-₹1,000 answer is: start with a ₹749 diffuser, and let the refill do the saving later. From ₹749.
One line: no true big refill is under ₹1,000, but a 50ml SOSA diffuser starts at ₹749 - then refill big for the cheapest per-ml scent.
Low budget? Start with a 50ml reed diffuser from ₹749, then refill big later.
