I have been using Paytm for about 3 months. I have also buyer some products from the site and the product which was delivered by the site was in a proper manner. The product was of good quality and I think I have purchased from the very good online portal. The delivery time was on time and actually the product delivered by them was of best quality. The paytm app is not only for online transactions and bill payment or recharge, it should be used for other purposes also. It should be used for purchasing quality products and in my opinion there are many such sites for online shopping which includes flipkart, Amazon and many more but Paytm site is reliable only when it is used for online transactions and recharge or bill payment.
