Remedy

Good news: I eventually got a call back from the supervisor at Cash4Books, and he told me that they would be sending the book back to me at their cost. I received an e-mail with a tracking number and shipping confirmation, so I should be receiving it soon. Although the whole situation seemed like one of those things a supervisor does to just smooth things over, even though he didn't really agree with me, that's fine. I've upgraded Cash4Books from my "do not do business with" list to my "consider doing business with if necessary" list.
