Which credit card gives the highest cashback on online shopping?

Credit score impact: each hard inquiry (which happens on card application) drops your score by 5-15 points temporarily. Applying for 3 cards in 2 months is fine IF you get all 3 approved. If 2 get rejected, you've taken a hit with nothing to show for it. Apply smart, not fast.

The customer care experience matters more than people think. I've had two cards with similar rewards, and the one from the bank with better support saved me ₹18,000 when there was a merchant dispute. Don't underestimate this.
