I am using amazon.in from last two years to buy products,
the service they provide is good.they take return if the product has some problem,
the quality of product is awesome.it look same as the image shown in website,
they take 24 hours to deliver a product, sometimes more.the app and website is nice they look similar together, the app take some time to buy a product, but website is good, the reliabilty is very good, any product can easily buy.
