Its one of the largest company in world in terms of online marketing.
But according to me I don’t think so because amazon.in is selling most of the other retailers product. So, without verifying that product in their warehouse the retailers easily sell to the customers.
If any of the product sell by amazon it self by its own warehouse the I guarantee it must be original.
Delivery timing is not good on amazon because most of the another retailers not dispatch the product on time in result it not delivered on time.
Apps and websites are design well and optimized properly even website is more secure during payment.
Some how it is not match with reliability as a result it decrease its rating.
