Probably because there are none. I think Gamestop had AR cards for the Pokedex 3D but they were for legendaries which most people got online. Haven't a clue as to where I find Uprising AR cards in the US though. I'll just resort to the internet.
Speaking of which, pretty envious of ya Jason, my cousin was going through and scanning a bunch of the cards online and for the most part, they were all European.
