I guess it's essentially an extra controller. I think CC was offering a free controller with purchase, too. Might want to check the CC and BB weekly ads, they've been running some with free controller or a good game.
If he ends up buying it there with a couple games, he might be able to split it. Buy the console with a $40 off coupon. Then, buy the games, extra sticks, etc. for $200 and use a second $40 coupon.
