Though there are too many sites but flipkart is a very great experience for online shopping. First of all, the products of flipkart are genuine and assured. I do online shopping most of times from this site. And when you dont like the product or if the product doesnt fit you or compatible you, you can easily replace the product or return the product easily and recieve refund after a couple of hours. I think the service provided by flipkart is great. Lots of categorised products available and there is freedom to choose. I personally like flipkart fir shopping.
