I am using flipkart from last three years.I like its service support.I also liked the fast delivery but the main thing is there is low discount on every product.but when we compare flipkart to other shopping sites so we get know that flipkart sell Smartphone at very low discount.And when you visit the Flipkart.com so you will get know that they are selling new smartphone at the same price.its delivery time is not so accurate.the flipkart deliverys the product atleast after twenty four hours.
