I don't really plan on buying any of my books until I've gone through the first week this semester because last semester I found that I never even needed HALF of the books I paid *lots* for

. And yeah buying them online if available always saves tons of money rather than buying them on-campus from the student store(s), fortunately since I'm in junior college most professors don't make their own books so I can save money with 3rd party vendors
