I decided I need more book space again, and scraped up two grocery bags worth of books I could do without. On the way over to Half Price Books, I was making a mental bet on how much I could get them for. I figured maybe $7-$10.
They offered $20. Woo hoo!
I came close to losing half of it with a book purchase (World Navy Ship Recognition Handbook) but managed to talk myself out of it. I win!
