Flipkart needs no introduction. It is one of the first e-commerce sites in India. With good offers, wide product range, covering a lot of regions in India(all urban and quite a few rural) Flipkart is currently the hottest e-commerce site in India.
Headquartered in Singapore, with Indias operating headquarters in Karnataka, Bangalore(Indias Silicon valley), the company was founded by two Bansals from IIT Mumbai in 2007. With a lot of investments the e-commerce site has developed a lot since then.
It has excellent user interface, simple to understand and use. Products can be searched easily and sorted according to price, name etc. The speed is also good.It provides quite a lot of offers. User can choose product that best suits him/her according to this offers. Delivery charges may depend on the seller/retailer.The product can be tracked after ordering at any time. You can get products position. The payment options are standard i.e credit/debit card, net banking, Cash on delivery.
The product replacement is possible but you cannot return the product after it has been delivered. I have been ordering products from Flipkart since 5-6 years now and only once I found a product to be defective. Replacement was easily done. Just login, and tell the reason for replacement, it will be done.
