I've had a tracker on this since I missed Cyber Monday. Down to $139.99 for both Cozmos (collector's edition, black, and the regular one). I just walked into Toys R Us that had them in stock and they quickly and easily price matched their website.
You can also get 50% off the Cozmo carrying case if you buy the collector's edition at my local store (I am in CO).
Rarely see these drop throughout the year. Little man will be happy XMas morning.
