There are many sites in Internet I mean E-Commerce sites but the reason why I selected Paytm is that it works as a site where you can buy anything and also as a bank like you can pay for taxies, Cabs and you can recharge your own mobile phone, you can link your credit card debit card with Paytm and even you can buy products on Paytm.
The best aspect of the site is that it offers heavy discounts and even sometimes offer hundred percent cash back that is very profitable for anyone you will get product cheaper than any other site on paytm, the worst aspect of Paytm is that sometimes Paytm sales the product at higher rate that you can that the product in cheaper rate from other site.
I have bought so many products from Paytm and recharged my SIM for many times and I even get cashbacks, so it is best to use Paytm to pay for taxis, cabs and recharge your phone.
I personally recommend to use paytm.
