I wonder if this is one of those situations where you can scam the scammers. Maybe go buy Jess a blue Best Buy shirt on Ebay, get her to hand out those concert-style bracelets to the first 100 people in line, and then go home, never to be seen from again. Of course, it wouldn't hurt to season that hundred people with some friends of yours. When subsequent people show up to wait for their consoles, they'll notice that all of the people in front of them have wristbands and they don't. And the employee that handed them out is nowhere to be found.
I know I'd go to another store - obviously I missed out on whatever the is going on.
