Which credit card gives the highest cashback on online shopping?

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.

On credit limit increase: most banks auto-review every 6 months. If you use 30-70% of the limit and pay in full, you'll get an automatic increase. Don't call and ask for it explicitly — banks take it as a sign of credit hunger and sometimes lower the limit instead.

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.
