I stumbled across a post by Kevin Tofel of JKontherun.com.  It talks about a great new technology that allows you to take a picture of a book, CD, or DVD, and it will instantly search the major online providers and give you available prices that are found.

G.W. himself was there & said he'd personally autograph a copy for the first one to purchase his book.
