Best credit card for online shopping with no annual fee

I've owned 4 cards over the last 7 years. The biggest lesson: a card that fits your spend pattern beats the 'most rewarding' card on paper. A 5% cashback card you actually use daily will give you 10x more value than a 10% card you use once a month.

I closed my HDFC card last year. The process took exactly 7 days. They sent a confirmation email and a closure letter by speed post. Tip: pay off the full outstanding and request closure only AFTER the payment reflects. Calling repeatedly with a zero balance is the fastest path.

I've been a customer for 6 years. The biggest upside is the customer service. The biggest downside is the slow mobile app. If you do most banking on the app, test the app at a branch before applying — it's surprisingly old.
