This Jawbone Jambox Wireless Bluetooth Speaker lists for $199 new, but we found them manufacturer refurbished for $39.99 at Tanga. Shipping is free to the continental US. That's the best deal we can find anywhere online. While this is a Bluetooth speaker, it also has a built-in microphone and a 3.5mm jack, so you can plug it in with a physical connection to your smartphone or MP3 player. Note: I have a Jawbone Jambox and was impressed by its volume.. Sales tax is charged in most states.
