Yet another vote for the library. If you are going to anything but the tiniest school, odds are they have a decent library that may already have your textbook, and if you don't have it, in all likelyhood they are part of an interlibrary loan system that does have your book. I haven't bought a book for more than $25 since freshman year (even made some money selling the books I did buy). The interlibrary loans were good for 4 weeks at my school with the option to renew for another 4 weeks, that should take care of a semester.
Also, if your school's library doesn't have a good interlibrary loan system, try the local town's library
