Walkin' man

[glatt]

This was all over by the George Washington University. And this is the time of year that the students are counting down the days until summer. And looking to make some extra cash by selling back books. When I was a student, you had to go to the bookstore to sell back your book, and they gave you around 10% of what you paid for it. Now there are numerous third parties that will buy them from you. Including a slew of hot dog vendors. "You want ketchup on that hot dog? Really, not mustard? Got a chemistry textbook to sell?" Ok. *Looks book up on laptop.* "I owe you $26 in change."
