Our Wal-Mart did this for the 360 and it got a good response. If we have 50 people show up, and there are 10 systems available, this is how we did it. We take numbers 1-50 and put them in a bucket. All 50 people draw a number out of the bucket. The customers with 1-10 will receive a unit. It seem to work without many complaints and was fair to all customers.. since they all had a fair chance of pulling out the 10 numbers.
By the way, our Wal-Mart only received 4 60 Gig and 2 20 Gig. So it will not be a very happy day for customers.
