I have used amazon.in to buy many products including some electronics like mobile, laptop, kindle, tablet.
Overall experience is good.
Product was delivered on time.
Product recieved was in good condition meaning not damaged during delivery.
Products were genuine meaning they were not of some fake brands but original as were mentioned.
Time to time great amazon sales occurs and they offers great discount on almost all the products.
There replacement gaurantee and customer support is good and you can return or replace product easily.
They provide delivery support to most regions of the country.
However their coverage does not cover entire country and theres much scope in this.Hopefully they will cover it soon.
