Which credit card gives the highest cashback on online shopping?

Two cards from the same bank usually share credit limit, not stack it. So if bank gives you ₹2 lakh total, splitting between two cards doesn't increase your available credit. That's a common misconception people carry when applying for their second card.

On the annual fee — most premium cards waive it if you spend ₹1.5L to ₹3L in the previous year. Wallet loads (Paytm, Amazon Pay balance) usually DON'T count. But utilities, fuel, and grocery do. Spend pattern matters more than absolute number.
