My personal experince with Amazon is pretty good . I have iphone . and I downloaded its app. whenever I feel to buy something I go to this app and order .
sometimes we dont get time to go out in the market and spend hours for shopping . but a apps like Amazon where you get more than crores of products and with no time limites. its open 24*7 so you can buy and add to chart you are fevorite product any time.
and most intresting like diwali navratri and indian festivals they offers huge sale n off on branded products so it helps customers to buy it .
