Brad's Deals Editor David,
Get this Yamaha WX-010 MusicCast Wireless Speaker in black only for $80.99 with free shipping at BestBuy.com. This was the best price we found by $19. You can use it as a stand-alone WiFi speaker, but it also works with other MusicCast-compatible speakers and receivers to perform whole-house or multiroom audio. It also works with Bluetooth devices. Sales tax is charged in most states.
