College bookstores are a racket There are already business models that have started to chip away at this type of racket. Chegg and Amazon rentals are decent examples. Sadly I'm unimpressed with the progress it has made. I'm convinced replacing expensive formally published textbooks with cheaper or freeware digital books is superior. The problem is with department deans and professors that hawk their own books in their courses.
