Well for my SimplyCLICK which is ₹500+GST=₹590 (starting coming Jan, FYF due to Amazon gift voucher), I didn't spend 1 lakh definitely to get a waiver but I did spend ₹40K in a year which earned enough reward points to get me ₹500 Amazon gift voucher (you can redeem it via SBI cards website or app). For the remaining ₹90, there was a "Pay bills worth ₹5000 total with SBI card across 3 months" offer recently which will give flat ₹250 cashback in December (I know meh, very less savings). But during Diwali, I got ₹3000 off on two big purchases on the SBI card. I keep the SBI card mainly for big festival offers, otherwise it's useless and SimplyCLICK is getting more and more de-valued every year.
My other cards - ICICI APay, OneCard, RBL BankBazaar SaveMax, BOB Select, IDFC First WOW (Secured) are LTF. I am a CC newbie - just got started this year in Jan 2022.
