Well in cashbacks and promotional offers , I prefer to buy at paytm.com because they are giving upto 80? cashback when you pay from your card which you can use by recharging or shopping. Also it has Brand new genuine products.
Their product price is also comparable to amazon.The main benifit of paytm is their wallet , you can do your recharge even if you don’t have data connection by just calling their toll free number. I will surely recommend this to my friends
