Paytm.com fisrt came with online recharge then they introduce wallet system and at that time the wallet payment option come into action.
And I like this site most because they dont waste money on adv by any actor of actress they just did cash back direct to customer and now days the follow the same way. So I suggest you all to go on paytm.com and shop from there and use paytm wallet for payment at everywhere and get more and more cashback in your wallet.
