Hdfc money back plus credit card features

yes moneyback and freedom are worst base cards from HDFC:) butttt keep using it minimum at the least then you might get offered upgrade in future (not guaranteed) but still worth a try to keep HDFC card in usage for it

I am just using my moneyback just for the sake of using it , in hope for future upgrades:) (but many says its not possible like a cursed card once you got it.. there is no way to upgraded have to wait and see)

I heard after getting MB+ they don't offer LE and upgrade too

Although benifits are also not much aggressive 

3.33% upto Rs 625 /month on amazon and flipkart.

I think on amazon and some other brands it gives 3.3%, base reward 0.3%, 500 voucher on 50K milestone in one quarter
