If this is a textbook that you need to have in class. I would say go to the print shop and order couple of copies for you and your classmates (They also want cheaper textbooks). I think the biggest problem will be to have usable binding as loose or stapled paper won't cut it. A print shop will have the machines and expertise to do it relatively cheaply.
I saw once pirated textbook in class and it was done like that. I think half the class had a pirated copy.
