NeweggFlash offers the refurbished Logitech Z506 5.1-Channel Surround Sound Speaker System, model no. 980-000430, for $39.99 with free shipping. That's tied with our mention from two weeks ago as the lowest total price we've seen for a refurb. (It's also $30 less than the best price we could find for a new one.) Features include a down-firing subwoofer, 75 watts RMS of total power, 45Hz to 20kHz frequency response, and 3.5mm audio input. Deal ends July 8.
A 90-day warranty applies, but it's unclear who backs it.
