I was able to pick up an Xbox 360 Arcade with a free $100 GC at Wal-Mart around this time last year. Since I used the GC immediately on accessories and a game, I got an Xbox 360 for $99.
This happened in the BF timeframe, so we're not there yet. When the BF ads get posted / become available, you'll have a better idea about that. Right now, no, there isn't.
