Walmart offers the refurbished Philips 2.1-Channel Bluetooth Soundbar Speaker with Subwoofer, model no. HTL2160/F7, for $50 with free shipping. That's tied with our refurb mention from two weeks ago and the lowest total price we could find by $9. It features a total of 60 watts of RMS power, a subwoofer frequency response of 20Hz to 150Hz, two tweeters, and Bluetooth.

A 90-day warranty applies, but it's unclear who backs it.
