Notice the tiniest difference here:
Switched printers for the book, new: lower price. Just in time for Xmas.
Xmas Tree and guitar solo. Fret work. Oh, never mind. Go away. Stop bothering me.
Personally, I think the books are worth about $9, or, at the most, $9.95. Lacking the infrastructure and support, though, I can easily live with the two-dollar difference.
