Well I can tell you that when you are talking about amazon it is all about CUSTOMER SATISFACTION.
Do you know the meaning of word AMAZON. If you ask me this would be Excellence.They have truely proved themselves not only in INDIA but all over the world.
Believe me I am neither working in it nor I have taken any money for it. However this is the result of the service and trust they have provide to their customers.
Next time when any thought clicks your mind to shop online. Go Amazon and buy.
