Book Returns

So I returned 15 books to the bookstore today and only made $85. What a bummer! I tried selling them already on ebay, but they didn't sell. I guess some money is better than nothing. I really need it now so I will take the $85, but jeeze. And there were another 6 books that they wouldn't accept. We are students and for the most part don't have much money. I think the bookstore is the biggest scam. They make so much money off of poor college students. The cost of books is rediculous!
