Crate & Barrel via the iTunes App Store offers downloads of SCRABBLE for iPhone, iPod touch, or iPad
. (Search for "download" to find it.) That's a buck under our August mention and the best deal we've seen for the game. (Without this discount, the iTunes App Store charges $2 for the iPhone version or $10 for the iPad version.)
Update: The link above will direct you to Crate & Barrel's website. Once you search "download" and click on the link via Crate & Barrel, you will be redirected to iTunes.
