And for the new SB account.

Not much of a credit card person here.. but heard/read that SBI offers some good cashbacks for on-line spends for one/some of its cards.

I am not aware of the criterion used by I-bank in selecting/approving for co-branded cards.. but no harm in trying for it too.

However other cards give better rewards or cashbacks on (non Amazon) on-line spends, I think.

Citi business is gone. Else they had some good options.
Now some PSU banks also offer some good co-branded cards with OMCs (oil marketing companies).
