Target put 'em both on clearance a couple weeks ago, that's what happened, Mike. So when they hit 50% off at a measely $10, they all but disappeared. I'd figure in the Land o' Targets out there that you'd still be able to track some of them down if you looked everywhere, but perhaps not.
I thought we would do well out here in the land of Targets too- but snowspeeders, kit Fistos fighter, the tins, mace's squad, and these GH 10 packs were gone overnight. For one thing, the stores really ordered very little of the product. I was hitting 3-4 targets 3-4 times a week before and after christmas, and never saw large quantities of anything except 1 store had 20 shuttles, and another had 40 plus snowspeeders. I was sure those would hit clearance, but one day I went in, and there were 2 shuttles left at full price- I was lucky enough to find one Mace pack at 9.99, and that was it. The snowspeeders sat in large quantities at 21.00, then were gone and I never even saw if they got marked down again.
The GH 10 packs, I never saw more than a single case on the shelves. I doubt the stores here ordered more than a few cases each.

I don't know if TRU is still getting them, but Entertainment Earth does have them. at 109.00 a case it is just a couple dollars more each than TRU- a far cry for $10 each though- that would have been sweet.
