Flipkart is a good site for genuine products the quality of the products is also good. though products are a bit more prized then sites but you can be mostly assured that the product is original.
The interface of of this site is good and search engine is also accurate but sometimes the site crashes.
The delivery is also very fast and accurate overall is recommend this site for a user who is looking for genuine products.
My list of online site goes like this. First place to flipkart for its service and original products. Second amazon for its prices .
