If you want to buy any. just remeber only one site that is flipkart. I alway buy product from this site. on this site their are geniune products if you want original product then you have to buy them from flipkart . and delivery of the product is also before time , just assume that today is 1 jan and the assuming of our product is 7 jan then u will definately get your product on 5 jan, if their are proper conditions. it is very rare that your product will be late
