Hi this is Pallab I’d like to use Amazon app for most of the time why because this app contains discounts coupons and more facilities. The delivery time is more accurate than other. very product of need is available on the website.the customer service is great.there is no need of hesitation to buy any product from this website or app. You have all the products quality verified by amazon. It has the best products with good quality. Presently there are so many sites and websites are there to shop online but the best I chose is Amazon which is a friendly shopping . And recently it introduced cash on delivery which is best for everyone . I purchased goods of around Rs.3500 in last 1 week.I am loving the experience.Fastest Delivery of all other websites but still I think they should give amazon prime trail for free .
