These guys just got a deal with Mark Cuban on Shark Tank. They let you rent textbooks for $5 a day. http://www.packbackbooks.com/

When I was in college, I figured out the textbook scheme by my second semester. We would buy expensive books and next semester the bookstore wouldn't buy them back because they were "outdated editions."

So every year after that, I never bought any textbooks. I would either find the professor's powerpoints online, or make a friend who did buy it and make copies of their book. If I absolutely needed a book I would rent it from Chegg or buy used off Amazon, but now Pack Back books looks like an even better solution.
