Half.com, amazon.com, tons of book resellers, used bookstores online, etc, sell textbooks at half or close ot half price, some WWAAYYY less. I've found that amazon has given me the best results, as a lot of the "used" sellers will often send new books or books that look perfectly new. I bought a $64 book for $16 shipped that way expecting something used and received a pristine package with pages that still stuck together like new
check online, save TONS of money. Or become a music or art major and spend more on supplies than books...
