When we had a book where only the homework problems changed in the new version we would pool together to buy one new copy and that person emailed out the homework questions.

The rest of us bought used books at the start of semester used book sale.

I think it worked best for everyone, I do wish I’d bought a few books new just for the longevity, but saving money was worth a lot more as a student.

When editions changed and problems were assigned from the books, most of the profs at my university would gladly provide copies of the updated questions. I even had a course where students would bring in photocopies of the prof's textbook to class, and he was still willing to pay a Knuth-esque stipend to students who found errors.

I had one that was the exact opposite, even going as far as violating the university policy by charging for quizzes. The administration refused to do anything about that one ...

I just went into the university bookstore & took photos of the question pages, lol. This was in the digital camera era, pre-smartphones, so it was hard to hide what I was doing and I got kicked out once or twice. Worth it to save hundreds of dollars.
