Should i buy a tv now or wait for some more days ?

My budget was 15k but after coins and coupon discounts i was aiming for the 20k tvs like currently realme 43 is in my mind but i have only sbi card and not axis and hence no discount and i need to buy from sbi only to meet the spends limit in order to waive my yearly fees off so wanted to know should i wait for some more days for another sale or should i buy the tv tonight only.

All kinds of suggestions are welcomed.
