Walmart offers the Logitech S-120 Stereo Speaker System, model no. 980-000309, for $6.99. Opt for in-store pickup to dodge the $4.97 shipping fee. That's tied with our mention from last October and is the lowest total price we could find by a buck. These speakers feature 2.5 watts RMS total peak power, 3.5mm headphone jack, and a 4.5-foot power cord.
