I am a regular customer of amazon. It is a global site so it is reliable. The main concern of this online shopping site is its customer service. I have tried almost all online shopping sites but the customer service of this site is just wonderful. they send the items within the mentioned date always, never delay. If someone wants to return the product then he can do it within the due date and will get his money back.
The product quality is good, but sometimes they give defected products, you just have to then return it.
Delivery of the products is moderate. you can also ask for fast delivery with the cost of some extra money. The delivery man contacts you if there is any problem with finding your address.
Amazon has also launched an app to get their customer more easily. You can also use their website if you don’t have the app.
if you really want marketing online then I will prefer amazon.
