I started haunting SAC specifically to pick up one of these (finally got it yesterday!). I ended up downloading the app to my iPhone, and setting the alerts. I have my phone with me most of the time, and was able to catch this one.
They had 11 of them originally, and were down to six with 7 minutes left. Then I had to go do something. Anyone know if they sold out? (If not, maybe they'll come back...)
