Probably not, since with consoles, it is hard to find them for below retail and it is very rare when there is a cpn that works on them. The only time I can remember a cpn like that was last November when there was a 20% off cpn that seemed to work on anything including systems at KMart. I guess it was working very early on after the cpn got out, but later on, the employees wised up to it and stopped taking them, it was very YMMV. But, a while ago there was another 10% off online cpn for KMart, and I was able to get $45 off of a 360 Elite.
I was able to get the GoW game for free from Sony, although those motherers drilled a hole right through the case. Luckily, they missed the bar code, so I was able to pull a switcheroo at BB for a good one. I wasn't gonna let those assholes up my collection like that, especially not on an awesome game like GoW. Anyways, that's the only deal I got for you bro.
