Hell yeah! Fuck textbooks and fuck the people who think a hardback is worth more than $75. The problem I had is that I always shelled out $300 for a massive Abnormal Psych book and when I went to sell it back either a.) They weren't buying the old copies because a new edition was coming out or b.) They'd give you $50 for it and re-sell it "used" the next semester for $150. Either way they swept up loads of cash on that shit. I had a friend who stole each and every one of his text books from the bookstore Sophomore-Junior year. Pothead though I was, I was always too much of a goodie two shoes to go that far.
Ironically, I always sold my books back for anything they'd give me because when you're poor and in college, you need beer money. Looking back on it, I wish I'd kept all those books, because Psych books make for some incredibly interesting reading sometimes.
Here's something else to chew on that may completely derail this thread, but I think I probably could have, with the exception of my English classes where we actually had to analyze the books we read, have earned a Psychology degree completely on my own using only my incredibly expensive text books. It really makes you realize how worthless your degree is in the end... basically, it's a certificate from a bunch of old people saying, "Yep... he read his $300 books and passed our exams," when if you'd just read the books on your own outside of a classroom, you probably would have learned just as much if not more.
