Hey, came across this today and didn't see any posts referencing it so here it is :)
The deal is for a black wireless controller + 4 XBLA games
Taken from Best Buy's Website:
Wrap your hands around the fun of a myriad of exciting games with this exciting pack containing a wireless controller and four thrilling games, including Geometry Wars: Retro Evolved 2, Lumines Live! and Bomberman Live on disc and a downloadable token for Ms. Pac-Man. The black wireless controller's 2.4GHz wireless technology lets you control your favorite games from a range of up to 30', letting you sit back in comfort as you work the buttons and feel the power of the adjustable vibration control. The Xbox 360 Guide button lets you keep track of friends, access games and media and more, and an integrated headset port makes it easy to savor the interactive fun of Xbox Live play.
The four included games will give you plenty of opportunities to test your controller capabilities to the max. Enjoy retro shooting fun in Geometry Wars: Retro Evolved 2, which comes packed with daunting enemies, thrilling powerups, multiplayer opportunities and more. Embark on compelling missions and solve challenging puzzles in Lumines Live! Scatter bombs to thwart your enemies in Bomberman Live, which offers online multiplayer for up to eight players.

Pretty good deal IMO
