The Apple TV is showing up as ‘Unavailable for pickup’ at Apple Stores across the U.S., with multiple NY Apple Stores we called saying that in-store stocks had been exhausted by demand created by the promotion offering $25 iTunes credit with every purchase, along with that generated by the upcoming London iTunes festival as well as the recent Lollapalooza livestream.

iTunes Festival is incredible in so many ways for Apple and its customers. It looks like they may have underestimated demand this year though.
