No... they sent a coupon to some people for 10% off the entire purchase in-store (including new games, guides, etc.)... more powerful than the More Card.
I just stopped into my local Gamestop today to find out if they had any new trade deals. Need to get some credit towards the 360.
I saw a sign that indicated that if you trade in the usual suspects (PS2, GCN, XBox - non-sports) you will get an additional 20% towards an XBox 360...
