I got mine, and used one last night at WalMart. I got the RCA with RF and Video Outputs. I haven't hooked it up yet, but I will probably later today.
There was a slight problem with the coupon, but it was due to the clerk not knowing how to use it. A manager came over and pushed a button, and all good.
That's a scary thought about the coupons arriving depleted... Hey, if they can do it to your bank account, they sure can do it to the government. There's probably a foreign internet fraud ring hard at work on it! Two $40 coupons x 250,000,000 people? Lot of dough to steal!
I got an iTunes gift card for my birthday, but it had been cashed in Jakarta, Indonesia a week before it was bought
