Which ECommerce website is best?

Nowadays there is a very huge competition among E-Commerce websites. They all provides great deals for its customer but the thing is "which website provides facilities for its customer"?

Personally speaking I like Amazon the most, it is besause they provide customer satisfaction, Like sometimes if the product you purchased is not what you have seen in the picture then you can claim on Amazon.

The Best thing is you will get your Money back.
