Reselling books

As with every semester, I start off by attempting to resell my books to the bookstore. This time I got a whopping $28! I went back into the bookstore and found that I could repurchase the same books as used for over $150. Something seems a little wrong with that. I guess that is how the USC bookstore is the most profitable college bookstore in the US. To make matters worse, the customer service man outside who purchased my books was the snobby/unapologetic type. A wholly unwelcome experience overall. I can hardly wait until next semester.
