I would say that Snapdeal.com is most reliable site to buy product from because it gives good customer service and day by day they are improving their services. What ever product you buy from this site those product genuine and the quality is also very good and if incase it comes out to be defective then you can exchange it. once you order any product from this site then this company gives some delivery period and they try to deliver on that time only. Snapdeal app and website are easy to use and also very reliable.
