That “Book Club Bundle” idea seems to have worked. Once anyway.
A group of four used copies of Cold Mountain for $2.50 (and we included information on some websites for discussion questions) took about a week to sell. Unfortunately, while we have two copies of several suitable books, we have four copies (minimum for a book club, I should think) of only one – Death of a Salesman. I am certain the reason we have four copies of it is that my high school teaches it to English classes in the junior year. I hated that book.
So – not an obvious pick, like Cold Mountain, but worth a shot. And I am going to be on the lookout for more.
