Brought a bunch of books in to sell, one of which was a modern mexicam cookbook that was brand new. They wouldn't buy it but I was moving so I told them they could have it for their "free" shelf. A couple days later I returned to sell a few other things, and they had the same copy of the cookbook (there was not a copy there when I came there originally, so I'm almost positive it was mine) on sale for $10! I asked a staff member about it but he didn't seem to know or care. This place is a ripoff. Donate your books or have a yard sale instead. You'll get more out of either.
