This Wireless Speaker System (model SC-NE1) drops from $199.99 to $99.99 plus free shipping at Panasonic when you use coupon code FLASHSPEAKER at checkout. This was the lowest price we found by $50 and the lowest price we've seen for this system. This uses Bluetooth to stream music wirelessly from a home network or from mobile devices such as iPhone and Android phones. Plus, it's a 2-way speaker system with 3-1/8" long stroke woofers, making it better than most mini Bluetooth speakers. Sales tax is charged in most states.
