Newegg offers the refurbished Creative Bluetooth 2.1-Channel Speaker System in Black, model no. T3150W, for $27.99 with free shipping. That's $2 under our February mention and the lowest total price we've seen for this system. (It's also $20 below the best price we could find for a new one.) It features a frequency response of 40Hz to 20kHz and includes two satellite speakers and one subwoofer. Deal ends September 3.

Note: A 90-day warranty applies, although it's unclear who backs it.
