idk but i don't. cause the expensive textbooks are not the $40 ones my upper level classes have. they're the $200 intro class ones where 1000s of students take the course from a single school and there's some shitty online access code bs paired with it.

also, it is def not "reasonable" to repeatedly re-release editions just to make old ones useless.

i usually enjoy reading the $40 upper level ones a lot more btw.
