Here in Tennessee, profs have to sign a form when they pick a textbook stating the cost. Unfortunately the deadline for picking books is about five months before the class, so some crappy, expensive books stick around because the time near the deadline is too busy to consider alternatives. Free books will only get you on the list for consideration.
