Well, I'll tell you a secret. This was a five-minute freewrite challenge, so I didn't go back and correct something I would have otherwise. The proprietor of the book store gave me $60 for my loot. I could have negotiated with him for more, but I was satisfied with what he offered. I spent the money on a nice dinner out with a friend. It was about letting go of the old so that I could bring in new experiences.
If you have books you'd like to get rid of, you can try calling a used book store if there's one in your area. They will often come directly to you and haul them away, which is also a big help.
