And now for some good news...
There is a book cart downstairs at work where you can pick up a hardback for $1 and a paperback for 50c. I was poking around, looking for a read, and found a children's hardback about the Baron von Hotzenplatck, or something like that. It seemed slightly familiar, and looked interesting, so I stuffed a dollar in the box. Then another teacher who is from Germany came by and recognized the title of my book. I offered it to her, but she said she'd buy it online, so I sent it home with her for just the time being.
This morning she found me in the office and said she'd looked it up online where it sells for $70.
I'm heading back to the book cart!
