Amazon is a very good app and website for online shopping. My experience is good and I’m satisfied with service quality. I have bought redmi 4 on 31 July and they deliver it within 32 hours to my home. The products they sell are very good and the price of product is satisfactory. It is a trustful website for online shopping. I’m using it from 3 years and I’m also a prime member of amazon.Thankyou
