I actually thought about doing this instead of taking them to donate at the library. I had a large stack of metephysical books I hadn't read in a while. I took them to the religion store by my house and sold them. I only got 15% of the publishers price, but some I'd been given for free, and a few I bought while I worked at a bookstore and got a major discount. So I got a $20 gift certificate, that I need to spend. Decisions, decisions.
