Groupon offers the refurbished Samsung 120-watt 2.1-Channel Bluetooth Sound Bar with Wireless Subwoofer, model no. HW-FM35, for $79.99 with free shipping. That's the lowest total price we could find for a refurb by $15, although we saw a refurb for $30 less in May. It features a 6" 120-watt wireless subwoofer, Bluetooth, and HDMI. Deal ends August 30 at 12:59 am ET.

A 30-day warranty applies, although it's unclear who backs it.
