This smells like a PR trick.
PR BS?
"This smells like a PR trick."
Uh-huh! I can't imagine someone paying $250.00 buying a book you can get for as little as $17-something at a discount store, but then I wouldn't take the book if you paid me $250.00 to take it!
GAAAAAAACK!
One thing that was common when Hillary Clinton was doing her book tour was that the copies were immediately put online at ebay. Some "fans" of the First Lady these people were.
www.bookfinder.com also allows you to see book dealers who sell signed and unsigned copies of books. Then again you can find the same book from different dealers for anywhere from $14.95 to $250 depending on how proud a book dealer is of his inventory.
