Three year back while filling oil at a petrol pump I got offered to have a Payback card, Although at that time I was unaware about the uses, but I just had it.
Then I visit the web site fro details, I found that so many online shopping sites have been tied up with Payback, then I started purchasing through Payback from jabong, inkfruit, flipkart, snapdeal as regular buying but I get some payback points which I use in future for redeeming some products. Then I linked my ICICI savings back, as I do swipe most of time and for that I get added advantages of Payback points.
So I am very much happy with this Payback web site and their service offered.
