Adorama via eBay offers the LG Electronics Music Flow P7 Portable Bluetooth Speaker, model no. NP7550, for $43 with free shipping. That's tied with our mention from two weeks ago as the lowest total price we've seen. (It's a current best by $7, although most retailers charge $70 or more.) This 20-watt speaker connects with up to three devices at once and features a rechargeable Li-ion battery, up to 9 hours of playback time per charge, and SoundSync technology (to receive TV audio in another room).
