I don't know about buying your books before school starts, I never do. It seems that I'd always buy my books according to what's needed for the class, then the professor changes his/her mind or and I need to get a different book. I nearly always buy my books online and most online sellers' return policy makes it nearly impossible for you to get your money back. I say go to class, be positive which book you need, then order it online with expedited shipping so you don't miss too much. Until then, see if you can borrow one from a classmate or talk to the professor about having a copy put in the library for those who do not have their books yet (you won't be the only one, I guaruntee it
).
If you buy your books on-campus and they have a legit return policy, then this may not apply to you, but if not, it's what most students at my school do.
