NES Classic Edition and Walmart.com

Available in limited quantities at Walmart.com, the NES Classic vanished in seconds. I had one in my cart but got several errors when attempting to check out. Of course, when I did manage to checkout, I got another error saying the item was not in stock (even though I had still one in my cart).

I guess that high demand wreaks havoc on them servers.
