Best cashback card for online purchases?

[snipergun22]

Can anyone suggest best card for online use
Bulk of my spend is online and i rarely use offline spends using my card as most are done with UPI only

Even thoug there are a wide varity of credit cards in marketplace
I suggest you to stick with 2 for ease of management

SBI cashback for flat 5% on most sites
Axis Ace for utility bill payments 5%

Beyond this you can look at Kotak Myntra card if you are interested in that category
