There's an auto-queue and at the time of writing this there's like 3600 people in it (and an estimated like hour wait), so no guarantee of anything being in stock by the time you read this; but I figured I'd post this in case anyone was waiting on them to restock. 
Thanks for the heads up. I had wanted to get one before their supplies ran out the last time. Hopefully there's something left for me once I get through the queue
