Amazon is the largest eCommerce site present in the world .it consists of very expensive products and no proper description about that product. Amazon has the worst exchange policy among the many E-Commerce site present. even in some cases if any wrong product is delivered there is no proper customer service and they ask us to return to the address labelled on the product from where it came and they say that they will return the amount we spend to deliver back to them and then after checking they will decide to send a product or not .I think Amazon would be best site for online shopping if it take care of its customer service and also with fastest delivery.
