I just unloaded a textbook my daughter couldn't sell by listing it on Half.com. It wasn't difficult and it sold overnight because I dropped my price by about $5 under everyone else. They underpay you on shipping and they take a hefty commission, but we weren't going to get anything for the book at the U bookstore (a new edition is being used at her university now) and we cleared about $30 on a book she probably paid $80 for. Not good, but better than nothing.
