Buying PS3 from someone who have waited in line?

[Van Strummer]

I am one of the few who really wants a ps3 for myself. I am from Norway, but going to New York for a vacation this week. Because I do not want to spend my vacation waiting in line I was wondering if I have any chance of just showing up when the stores open and try to buy one from one of the guys who have waited in line?

What is the best approach to do this and how much should I expect to have to offer?
