I do think books cost way too much. I honestly don't think it costs anywhere NEAR $25 per book to get them on the shelf, even AFTER considering all the overhead. And I don't know if you've looked at the price of paperbacks lately, but it's insane! Some of them are $14!
Same goes for textbooks. When textbook manufacturers produce the exact same versions of American textbooks with different covers, then sell them for 75% less to foreign countries, something is wrong. The gouging of American consumers is an epidemic, and it happens in other industries too (most notably, the pharmaceutical industry).
I'll stick to e-books, discount bookstores, and international versions of my textbooks.
