What i did was a little trickerty.

I went to the first walmart and they were handing out cards to get one. Once i got my card i ran to another walmart and bought one there. I then left and went back to the first store. Changed my hoodie in the parking lot and asked the guy handing out tickets if this was the line for the HD-DVD player. He then proceeded to hand me ANOTHER ticket. So i bought the one that he gave me right there, and after work, hopefully he won't be there, i'll be able to pick up my third one FTMFW!!!
