Like I said earlier in the thread. By me in NJ these have NOT been hard to get at all. My local KMart got in another shipment of these the other day. I saw them, only had cash on me, but not enough so I returned the next day and they were still there, so I grabbed one of the Jedi Temple Assault and one of the Imperial Throne room for a fellow NJ collector to help her out.
Other than that, since I've had my for a couple of weeks now, I really haven't been looking "hard" so when I can randomly walk into a KMart, and they have it in stock, I don't consider it a "hard to find" item.
So I guess that's good - KMart must have ordered over the minimum required quantity on these. I figured that the three blue clones would be a no-brainer and fly off the shelves.
