Meritline offers the refurbished Logitech LS21 2.1-Channel Speaker System, model no. 980-000058, for $19.99. Coupon code "MLCKA16FNL1" cuts it to $15.99. With free shipping, that's $4 below the lowest total price we could find for a refurb elsewhere, although we saw a new unit for a buck less two weeks ago (since expired). This 7-watt RMS system includes two satellites with 2" metallic drivers, a down-firing subwoofer with a 4" driver, and remote control. Coupon expires after 100 uses.
