Till know I have purchased many product from Flipkart and every time Flipkart makes surprised to deliver an product before time. The products are genuine and cost is also reasonable. I love buy any product from Flipkart. I would to like share my own experience with flipkart. Till now I have purchased 4 mobile phone and many other things. among four one phone performance was not up to the mark. so I request to replace my phone with new one because they have given option that if feel any problem with the product. you can change/return product within 15 days from the purchase date. And Flipkart replaced my mobile with new one within a week. The courier service is also awesome.
