I'm trying to figure out if there are online-website codes that the book-store books have or *something* that would account for the discrepancy before I buy because I don't want to be stuck with the wrong books. But surely not *every* text-book is going to come with this extra stuff or whatever it is that makes the book-store different? So should I just buy online, and hope for the best. Or wait until the start of school and get fleeced?
(I would just go check the book-store but I live too far away to make travel to Seattle possible until start-of-school/move-in)
