There are hundreds of shopping sites today but I like the most is paytm.com. It has amazing cashback offers.you have to pay full amount and discount will be credited to your paytm wallet after 24 hours of shipping your product. I have purchased many products from paytm and everytime I have found much much better price options than other sites.
Recently I bought a 13000 mah ambrane power bank from it for 640rs.i have compared prices on all other sites and found this product above 1000rs on all sites.their delivery is little bit slow but they sell high quality products.
If any one wants to transfer his paytm wallet balance to his bank account paytm charges 4% service tax on it.they also have return policy, if you are not satisfied with product you can return it.one thing I dont like about paytm is that it doesnt give full information about the product and also doesn't provide good pictures of the products.paytm should work on this.apart from this paytm is very good shopping site.it has very less prices compare to other sites.
