I am using flipkart from the begining and I have never a single chance of a complain what so ever. All the products are good and original the price is reasonable.
Even my friends and family members use flipkart. Once I have ordered a french dictionary and some oages are defective ie printings are blurry. So I call them up and after some simple information they book my complain. I got it replaced within a week by a fresh new one. Other tgen this I have no chance yet to complain about it. My friends and family also have very positive experience with it. But recently I think the price in flipkart is not as reasonable as before it was but other than it just fine.
