My library sells books every few years. The last time I went to the sale, I scored one of the Feynman lecture series books for under a buck. When I handed it to the librarian with my money, she said "oh my", realizing that this was really not something they should be chucking away. If not for the fact that they charge annoying fines, I would have let them off the hook, but I said "well, you folks put it on the table for sale" and walked away with a fine prize.
