Amazon.in is really a worth site to shop online.
I am telling on the basis of my shopping experience with them.
This site offers great discounts with quality products and fast shipping with proper and safe packing methods so that the product does not get damage.
They also run great exchange offers on product which is a cherry on the cake. But if you want great amazon service than always buy product which are amazon fulfilled. It means that before the product reaches you it will first be analyzed by amazon if there is any defect , and than after confirmation it will ship it to you.
