As one of its daily deals, Woot via Amazon offers the refurbished Vizio 21" 2.1-Channel Sound Stand, model no. S2121W-D0, for $78 with free shipping. That's $2 under our December mention of a refurb and $26 below the lowest total price we could find for a new one. It features an integrated subwoofer, Bluetooth, and wireless remote. Deal ends today.
Note: A 90-day warranty applies but it's unclear who backs it.
