Amazon is a very popular and trustworthy website.
In my opinion, Amazon is the best online shopping site. It has the widest range of products. The products are genuine and to be honest they sometimes tend to be defective, but again it happens with all the online shopping websites. Amazon is very responsible and has a good customer care service.
I have been using Amazon for over 2 years now. I havent faced any major issue till now. The payments are also very secure and so dont have to fear from online payment scams while shopping from Amazon.
Orders are mostly delivered in time. The app and the website are beautifully designed. They also have a very good 24 hours customer care.
