Book Fair

Will, ever the reader, decided to set up a "Book Fair" in our hallway. He was charging 1-cent per book, with a limit of 4. But, he's evidently learned a thing or two from his Uncle Cory. Books just went up to 4-cents, no limit. But, when I picked out my 3 books, he told me I owed 75-cents. His reason? "The price is going up and the store is about to close, Mom."
