Query: College textbook price-gouging going on here.

$67 for a paperback book is highway roberry.Have been pricing out college textbooks on Ebay, Amazon, and the college bookstore. It's a bloody medieval guild these publishers have going here and professors who insist on the latest editions of texts are aiding and abetting the rip-off.This is monopolisitic practice if I've ever seen it. If the industry doesn't rachet down this greed-fest, someone else will - and as far as I'm concerned, it can't happen too quickly. Shame on you all.
