Do online sellers sell fake product?

A BIG YES!!! See it yourself here:

SNAPDEAL - A big name in the market. I found this Logitech mouse on Snadeal. Adding the link and snapshot here:

Logitech B170 Black Wireless Mouse

I thought that it is sold at very less price for a Logitech mouse so I went to Logitech site and tried to find this model, but I couldn't.

Then I did some more research and found this :

Import Data and Price of logitech b170

Yes. That's correct. They imported 4000 pieces of this mouse from China at 381 rupees per piece. When the buyer feels happy for saving couple of hundreds after buying this product, Snapdeal gets the devil laugh for getting some 200 + profit per unit after selling the product.

A win-win situation for both I guess!!!
