Campus bookstores do make a little off of textbooks they sell there, but online textbook brokers have nearly killed that system as well (which is good). But, in the end it doesn't matter...if they don't get the revenue they need from the bookstore, they'll get it elsewhere.@Pokinfun: if the textbook proceeds go to the school, then they need to make that cost included and flat. My engineering textbooks were WAY more expensive on average than my business and art school friends' books were.
