Dangit! Now I'm gonna have to hound HBTS for a Junkheap and Prime Starscream. Thanks for the heads up, and for the coupon animalspinners!
Also, they're not TRU "exclusive", TRU just happened to get them in first for some reason (possibly, limited time exclusivity, or early release rights). I think it also might be that other retail chains don't want to order a new line when their back rooms are probably full of over-ordered movie figs...
