As one of its daily deals, Best Buy via eBay offers the Logitech Ultimate Ears Boom 2 Portable Bluetooth Speaker in Indigo for $98.99 with free shipping. That's tied with our expired mention from a week ago as the lowest price we've seen. (It's the best price we could find now by $31.) It features a 3.5mm auxiliary input and up to 15 hours of music per charge. Deal ends today.
