As one of its daily deals, Best Buy offers the Marshall Kilburn II Portable Bluetooth Speaker for $229.99 with free shipping. That's $20 cheaper than the best price we could for a refurb elsewhere (this one is new) and at least $69 less than a new unit. Features include a 62 Hz to 20 kHz frequency response, 25-watt RMS system power, and up to up to 20 hours of playback on one charge. Deal ends today.
