I have been using this website for more than 8months. The best thing is cash back offers. Even though the website is good, delivery is so bad. Mostly I buy books. When I ordered in Paytm, the delivery took more than the given period. It may be nearly 20-22 days. I have orderd nearly 6-10 books. All books delivered with folded and spoiled edges and corners. One of the books delivered with marking of folded into half, spoiled corner. The card board in which the book is packed was also not up to mark.
Finally I would say, even though offers make it good, delivery makes it bad.
