Flipkart is one of the famous online buying sites in india.As it is known for its service
I ordered a pendrive of Sandisk USB3.0 from flipkart which I got within two days and I was not in any metro city, i was in bhubaneswar at that time.which is very quick.
Flipkart will never disappoint you regarding the quality of the product.
But one disadvantage is there if you order it in flipkart.it cost you a little bit more than what you get in amazon and snapdeal.
So its service is very good but the price on the product should be more practical as they are not the only seller in the market.
