In college I just didn’t buy textbooks because they were rarely necessary. A few classes (economics in particular) sometimes assigned homework problems in textbooks which would be randomized between editions so I couldn’t get a cheap used version. I just asked a classmate if I could take pictures of the relevant pages and never had a problem.
