In the past I've shopped the heck out of my textbooks. I'd find them on eBay, half.com, or whatever site was selling that particular book the cheapest. Then I'd plan to sell it on eBay when I'm done...but I never do.
That is, until recently when I discovered chegg.com. I rent the book, they ship it to me. If the class gets canceled I send back the book using a prepaid label they provide and they refund everything, including shipping. If I keep the book for the semester, when I'm done I send it back with a prepaid label they provide. Piece of cake! No hassle and it's way cheaper than forgetting to sell my books when I'm done.
I figured there's probably some others here who might be able to use it.

Cheapest eBay/half.com/web price I could find was about $50, and I didn't bother checking if that was the correct edition or not. I could do better if I buy the $50 one and sell it when done, but probably not much better.
