Can someone tell me the best place/shop in Kanpur to resell my books ? They are mostly NEET related books.

Which is the best shop where I can resell my NEET related books ? I want to get best prices as possible (atleast I don't wanna get ripped off). Have some financial issues recently so want to sell books which I no longer use. Recently had a bad experience with Sanjay Book Depot , Parade so it's a big no no ! Please give addresses as well of the shops if you mention.
