Creations for Charity has opened up their Bricklink store and has begun selling their donated creations today! Even if you're not into MFZ, there are some really awesome models for sale from some very talented builders.
My Pit Vipers, Shorties, and Freedom's Breath companies are still available and are going for $200, $75, and $75 respectively. The Tin Men have already sold, so I wouldn't expect the others to last very long. Get on over there and get yourself some sweet Lego while giving underprivileged kids the same joy you get from this wonderful hobby.
Update: the Pit Vipers have sold! The other two remaining are the more affordable options and are still available.
