Low on power? Staples has a White Xbox 360 Battery Pack for only $6.97 (Available in-store and online) These battery packs are for people who already own a play and charge kit and need another battery for their other controllers.
Unfortunately it looks like only the white one is on sale.
Try luck price matching Futureshop or Best Buy for an even better deal!
