My buying experience on flipkart has been great when I bought my lava ivory tab which was available there at lowest price among all eCommerce website.
Once I ordered a tshirt that time my experience was a little bad because due to inappropriate size I had to change and for my refund I had to call the flipkart customer health many a times a day. So for that I wanna say that flipkart is good but when it comes to replacement it not as good as amazon
