NeweggFlash offers the refurbished Sony Ultra-Slim 2.1-Channel Bluetooth Soundbar, model no. HT-CT390, for $129.99 with free shipping. That's $9 under our refurb mention from three weeks ago and the lowest total price we've seen in any condition. (It's the best we could find for a refurb today by $68.) It features a wireless subwoofer, Bluetooth, and USB.
Note: A 1-year warranty applies, but it's unclear who backs it.
