As a student, you are strongly aware of the high costs of textbooks. Moreover, you might have noticed that every time you purchase a textbook, you receive a pitch from the publisher to upgrade for some extra add-ons without which, according to the publisher, you will struggle to understand the course and excel in your studies.
