I am using Amazon prime and it is the best e-commerce website. They provide the best customerr service. They provide us with genuine products with great puntuality means the delivery time set by them is the dead line for them as product reach to me before that time. I think that product quality mainly depends on the price of the product as when I have purchased a dog collar its was 210 rupees so the product reach to me was not so well packed and when I bought shoes which was worth of 2000 rupees than it was well packed by amazon means they are more eager in providing best qualities to those who buy product which cost above 1000 rupees.
They deliver their products on time.
I prefer app because it much faster than website
And I can easily buy a product at any time .They are very much reliable as they give us genuine product no first copy or replica .Even in case of protien they are very much trusted so all of u dont wory about the original product and buy from Amazon.
