Altatac via Walmart offers the Ematic Ultra-Slim 2.1-Channel Bluetooth Soundbar, model no. ESB210, for $49.95 with free shipping. (Action Gear via Amazon offers it for the same price.) That's the lowest total price we could find by $30, although we saw it for $10 less in August. This wall-mountable soundbar features an LED display, Bluetooth 3.0, USB drive with MP3 decoder, RCA input, EQ presets, 3" subwoofer, and includes a remote.
