Do you/Did you sell back textbooks in your major?

[PhiAlpha05]

My situation is probably not typical, since I'm pursuing academia, but I did end up borrowing and returning/reselling several textbooks that, now, I kind of wish I'd kept. Granted, the types of books I'm talking about (music) are not updated nearly as often (or given updates with as much critical information) as yours are. If you think your current editions will be outdated in a couple years, it's probably best to sell them now while they still have some resale value (which will tank once a new edition comes out) and spring for the newer editions if/when you need them.
