I have sold five so far. :) Turning five useless books into $50 makes me happy. Jared says I am wasting my time and should just donate them. I'll give them a year and donate whatever doesn't sell.
I enjoy visiting the post office to mail them. The postman is very jolly. The boys just stare at him. When do children learn it is rude to stare? If it were warmer I would walk over to the post office, which would be even more satisfying.
