Checked and didn't see this posted, I do believe it just started yesterday. I was actually at blockbuster trading in, before I got an email from them, telling me about this promo, :lol:
I missed out on the GoW promo, like this, didn't want to make the same mistake twice. Even though I'm not as pumped about Halo 3 as I am some other 360 games, you can't go wrong with a simple trade in to get it free, especially if you have some games around that you no longer play.
