textbooks

I bought my textbooks at Stony Books at the beginning of this semester because I thought they would be cheaper there rather than at Stony Brook's bookstore or anywhere else. I chose to receive email notifications to let me know when I can start selling my books back for cash.. so a few days ago, I got the email. It listed one book that I paid $10 for and they said I will get 25 cents back. That's right, a quarter. What am I supposed to do with that? Maybe I can put that quarter towards textbooks for next fall. Out of the $300+ I'll probably spend on books, I at least know I have 25 cents saved up.
