Bose via eBay offers the refurbished Bose SoundLink Mini Bluetooth Speaker for $129.95 with free shipping. That's tied with last month's mention and the best we've seen for a new or refurbished unit. (It's also $19 under the best price we could find for a new one). It features a 7-hour run time and a charging cradle.

Note: A 1-year Bose warranty applies.
