[Edit: sold out!]
Circuit City.com has Nintendo Wii consoles in stock and available for order.
They require you to add an additional wii remote/nunchuk (which you need anyway), plus one game. Free shipping is available on the entire order, or you can check for in-store pickup (not as likely) as well.
These typically sell out quick, so snag one if available...
