Flipkart.com has gained trust of customers over the past years. Coming to personal experience, whenever I have ordered anything, especially electronics, they have served me right.
Although some times I have got the wrong product and customer services have helped on the spot. This site is trustworthy and you won't waste your money shopping on this site. I have ordered many things like phones, laptops, speakers, tvs etc and they were on time. Hope you too experience the same.
