Can anyone tell me how the Thanksgiving deals at Walmart work? We want one of the iPad minis, which Walmart says it has a "one hour in-stock guarantee" starting at 6pm. So how does that work? Do you still have to line up well in advance? I read something about individual lines for certain products and wristbands...I'd just like to know exactly how it works before jumping into the madness! 
Thanks so much!

Thanks so much!
