One of the reasons I stopped collecting Star Wars minifigures was that there was too many exclusive minifigure popping up all over, making it nearly impossible to collect them all, not to mention the inflated prices on ebay or bricklink.
Star Wars fans will be delighted to find that an exclusive Clone Trooper Lieutenant Minifigure was released last weekend at the Star Wars Days at LEGOLAND California. Details of how this minifigure was given away are a bit sketchy, but it looks like they were given out to volunteers from SanDLUG and LUGOLA and also as prizes in a 501st Droid Hunt game for children.
Hopefully as this minifigure is a polybag it will be used as a promotional giveaway by the LEGO Shop in the future. Good luck trying to get him!
