I do not like this app is not clean and it is deficult to operate also. the concept of amazon I didn't like much better because I purchase study material books from Amazon for my friend its packaging is whorst and some books are defected. I didn't complain any thing because I lives in village so there is no such facilities in ower village. In ower village if any one want to order some thing then we have order product near village where facilities are provided their and the main thing is when I buy this books it cost is 2999/- but in other store books price is 2499/- so pricing of Amazon is more. So I didn't like this app
