@OP that's how sales are all about. It's a lottery game.
Here, My APrime 1499 voucher that came with HDFC Bizpower spend offer was expiring on Sep 25th so I activated it on Sep 21 and on Sep 22, order the product I needed i.e Samsung M36 5G mobile phone for brother as his previous POCO X4 Pro died on Sep 15 beyond repair as Motherboard burned out due to overheat and processor also died out completely.
I don't plan or look for these sales. Yes, during sale, if I find something that I can get at deep discount I buy i but don't look for items for which world is crazy. But again these deep discount items are factory faulted items i.e rejcted during inspection or returned items which are repacked.
As I always say, you end up spending more with such market gimmicks then savings. People spend every year on unnecessary things in life.
Unfortunately at Samsung website most phones are OOS so couldn't buy from there else till last year I always bought from Samsung directly. Gave me better discount then BBD/AGIF.
Try your luck during Big Diwali Sale.
