If you think that amazon is great for cloths so please stop thinking this because this is not good for cloths. but if you want to buy some other products like books you can buy and electronics as well. delivery time is good and customer service is okay. never get shocked if you brought some thing branded in cloths and shoe and your known says that this is not real brand. because it is not selling 100% real brand.
if you want to become a seller on it you can try your luck. Amazon has no offer coupons but it gives great discount on festival so DO NOT BUY THINGS WITHOUT OFFERS BECAUSE SALES TIMES IT GIVES YOU A GREAT DEAL EVEN YOU CANT BELIEVE. use website for buying or shopping do not use app because app shows small icon of products.
