BeerMoneyBooks.com

BeerMoneyBooks.com is an online textbook buyback company, and they will purchase your used books and pay you cash. And their assumption is that you can then use that money to buy beer; which is quite a novel idea. Selling used textbooks is a great way to earn a few extra bucks, and it's also a great way to earn a little extra beer money.

BeerMoneyBooks only buys student editions, so don't send them instructor editions, international editions, or other special edition books. Sometimes new ISBN stickers get put on books, so check the copyright page for the original ISBN. Use that one when searching on their site. If they are not accepting it, then they won't give you an offer. If you have any more questions about their policies, check out BeerMoneyBooks's FAQ page.
