As one of its daily deals, A4C offers the refurbished Logitech Ultimate Ears Boom Portable Bluetooth Speaker in Black, model no. 980-000678, for $99.99 with free shipping. That's $18 less than the best price we could find for a new one, although we saw another new one for the same price in December. This wireless speaker features a 3.5mm auxiliary input, NFC, and up to 15 hours of music per charge. Deal ends today.

A 90-day A4C warranty applies.
