The Executive Jacket cover for Kindle is $14.99 with free shipping at Icemonkey, as of today, 11/22/2011 (US Pacific time). Although this isn't as nice as the $9.99 Daily Steals deal a few weeks ago, it's still not bad. I believe this fits the Kindle Keyboard (maybe someone can confirm???) and so would match up nicely with the Best Buy $89 Kindle Keyboard SO deal that's on (stock permitting) through 11/23.
Icemonkey deals are around for a while, until they run out of stock. The "stock meter" on this one is already running pretty low, however, although ***very occasionally*** the "stock meter" on Icemonkey deals mysteriously replenishes itself. Still, if you're interested, I'd head on over there soon.
Best Buy deal thread:
Although it says "choice of 4-colors" there really only are three (black, blue, pink) - the green doesn't seem to be available.
