They had these at a Walmart in Jacksonville, Florida for $35 about a month ago. That store has since sold out and the few others I've checked still have their Guitar Heroes in the game cases not in the clearance aisle, so I'm not sure if this was a one store thing or not.
I printed the ad and Target did honor it for Halo 2. They werent happy about it and took my copy of the ad. But after a few valid complaints about wasting my time and how they should honor their own ads they finally caved in. Halo 2 and Burnout 3 for $30, cant beat that!
I tried to use it Monday afternnon and was denied. They said they had just gotten an email from their main office that the coupon had been leaked and was no longer valid.
I paid $20 for it a while back and certainly got my moneys worth out of it. If you dont like the 'builder' games than no, obviously I'd pass on this. But if you like this kinda stuff then it doesnt get much better than this IMO.
