So, it's 11:30pm, I go to the local EB in town to pay the remainder for my xpac. They tell me that they ordered 150 copies, and had 270 preorders, so i better go and get into the line right away. Good thing I did, because 5 minutes later the line was packed.
Anyways, I get my xpac, and sort of wait around in the background. About 20 minutes later, a scream comes from the EB entrance, a 360 still in the box comes crashing throughthe window of EB, and people start running.
So, of course, I piss-bolt to my car, lock the doors, and get the hell out of there.
Moral of the story; Supply must ALWAYS be greater than demand.
