Well, that trend does not seem to want to stop, as fellow Seibertronian Optimutt lets us know from Walmart stores and their clearance sales: Titans Return Sixshot is currently available for the silly low price of $25.06 USD! If you ever missed your chance at picking up the wolf/tank/ship/armored car/submarine (totally not an upside down gun) which also turns into a robot in its spare time, and its Titan Master partner Decepticon Revolver (like the gu-- submarine), this may the be the last call before the upcoming holiday period!
I don't know if this counts as a sighting, but WalMart has got Leader Class Hasbro Sixshot on a clearance sale of the REALLY low price of $25.09.
It might be worth getting hold of now, if you missed him earlier.
