Spend much on books lately?

CampusProgress.org has an interesting article up explaining “[w]hy you’re being forced to spend so much on textbooks.”

A Government Accountability Office study found the average was $900 per year for the 2003-2004 academic year. The report also found that between 1986 and 2004 textbooks prices increased an average of six percent per year, well above the rate of inflation.

What are your money saving techniques? Me, I just buy the books, but I try to get used ones if they&rsquo're in nice shape. I also tend to keep my book... the ones I don&rsquo't want to keep are usually never worth anything anyhowways.
