LOL, my closest store is so incredibly fubar'd. Went at opening and they only had the Stark (10+ each blu and DVD) packaging and regular ones (20+ each blu and DVD). Asked for the Targaryen cover, and spent half an hour there as various employees went back and forth to the stockroom/back looking for it as the computer indicated they had 12 of them in stock. None were in the pre-order/online pickup area. They couldn't find them and blamed it on "a third party company that stocks the bluray/dvd section" (which is a complete disaster).
Second store I hit had only 2 left of the Targaryen version blu (none of the DVD), tons of Stark (20+ both blu and DVD) and tons of the regular (20+ blu, 50+ DVD). It also had 12+ each of Mass Effect 3 CE for PS3 and X360 available in the game storage cage, LOL. According to online inventory tracker, the Targaryen one is sold out at most stores near me already, but all show the Stark as available. I'm assuming they made equal amounts of both versions, but who knows?
I wonder what the dragon (easter) eggs are? Hopefully one of them is the "target exclusive" special effects featurette...
