How much are used movies and PS2 games worth?

I have the opportunity to buy four Sony Playstation games and a bunch of movies from a friend who needs the money.

He is liquidating a lot of his stuff to pay bills (lost his job) and taking his VHS tapes, DVD movies, and PlayStation games to CD Warehouse (a used media buyer/reseller).

Thing is, they only pay a few dollars for each item, so it's really a bad deal to sell stuff to them.

Nonetheless, if I don't buy it, it's going there for cheap.

Please let me know what a fair price for used media is, so I can offer him a fair deal--hopefully better than CD Warehouse will.

Thanks,

General Tsao
