A used book store with an amazing location just down the street from the Pearl Street Mall. They don't have the most stellar collection of books but in a pinch they'll do.
I'm not fond of the proprietor. I'm sure he's a perfectly amiable guy when he wants to be, but his demeanor while at work is something akin to Lurch from the Adam's Family.
I will give him this, however. Once I tried to bargain him down on the price of a book. The book was $6, and I offered him $4. Instead of simply saying yay or nay, he suggested that we flip a coin. If I won, I could have the book for $4, and if he won I would have to pay $8.
