answer:There are loads of resources online for buying textbooks, no enrollment required. You could pay a visit to the university bookstore, see what they have and what’s required for certain classes, then order them online. I never buy textbooks from the bookstore if I can help it, I just refuse on principle. First of all, it’s a total racket. The publishing companies put out new editions every year or two so you can’t sell back your books, even though the changes are usually minimal. Even if you can sell them back, you get a paltry fraction of what you paid originally. I’m appalled that they take advantage of a population that doesn’t have much money to begin with (students). Anyway, the first site I usually check is Half.com. There’s also textbooks.com, gettextbooks.com, Textbooks at Amazon.com, Textbooks at AbeBooks, BigWords.com, ValoreBooks, Textbooks at Barnes & Noble, and loads more. :)
