I was able to get my Black Friday ticket right at midnight but judging from the AX Twitter the available tickets sold out in about 10-15 minutes. I was already logged into Eventbrite and on the page when they went on sale. They did announce the sale tickets would be limited.
I remember last year they were limited and sold out before the day was over, but not that fast.
We'll see how this year goes. As a photographer I spend the majority of the time outside which you don't even need a badge for. It is convenient to be able to go inside to find people or use the bathroom.
