I have used the services of Paytm in India for a very long time. Earlier, to recharge my cellphones and later for a seamless, competitive priced online experience.
I have used the site to order food, pizzas, shop for clothes, cellphone, mobile accessories & even purchased a Treadmill. Their Wallet system & Cashback is unique & adds a lots of value to the shopping experience. I would strongly recommend Paytm for their services!
