In my opinion this is the best online shopping site.This site always delivers genuine products unlike others.They are very punctual about their delivery. Amazon has wide variety of products.Once I bought a Laptop from them I received it on next day only( I was registered for Amazon Prime) .The refund is very smooth. Once doesnt need to worry about redund.They process refund very fast compared to other ECommerce sites.If you compare price among different sites most of the time you will find Amazon has the least price.
