I am using this app for shopping since last 5yrs.Amazon has got the best products.But the service provided by it is average.Returning policy is not that much good.I ordered a sunglass before 2 months but the product quality was not upto the level.So I wanted to return it but these products could only be returned through postal or speed post.why amazon does not provide door step return like Flipkart! .Rest thing is good but this return policy should be changed
