How important, do you guys think, is the right edition of the textbook? I mean, I heard that the authors get a ton of money just buy editing a couple sections of, say, the gen Chem book and publishes that as a "new" edition. The prices are drastically different for a 5th edition as compared to a 6th edition. Any past experiences with how different the different editions of the textbooks are? Thanks!
