ChubbiesTech via eBay offers the refurbished Refurb Harman Kardon Onyx Bluetooth Speaker for $59.99 with free shipping. That's $58 under the lowest total price we could find for a new one. It features four 15-watt drivers and a 60Hz to 20kHz frequency response. Deal ends February 15 at 11 am ET.
A 30-day warranty applies, but it's unclear who backs it.
