I use flipkart since previous year and never found any issue from flipkart soI choose flipkart as best shopping it has nice service, fast delivery and good payment return process. The app of flipkart is user friendly as compared to amazon and snapdeal. There is option of cash on delivery you will be pay when you the product in your hand.
One month ago I buy product from flipkart and return it or I recieve money in 24 hours this is the best feature I like flipkart more than another online shopping.
