A pal from New York reports that there are copies of STP on shelves. It's earlier than I expected it, but not much earlier. If you do happen to be in a bookstore and see it or get confirmation from an online source, please drop me a line.
And yes, TFD needs to try decaf. ;)
UPDATE: BN.com is showing the book as "ships in 24 hours." That usually means it's in stock and Amazon is seldom far behind.
