It is my own experience that is , I had ordered the lenovo vibe k5 mobile in the Flipkart one month ago and they took 3-4 days to deliver the mobile. It is one of best servcer or delivers in India and it was in first rank in delivery but recently Amazon has become top . Everybody says Flipkart service is better than Amazon service is . We had ordered alot of materials in Flipkart and employs of Flipkart have delivered properly without doing nonsense work and yet they have not cheated to anyone. In my view flipkart is the best .
