Quick Ship Electronics via eBay offers the open-box Fugoo Go Portable Wireless Bluetooth Speaker 2-Pack in Black for $40 with free shipping. That's $10 under the lowest price we could find for just one factory-sealed unit ($60 savings for two). It featrues dual 52mm drivers, IP67 water resistance, and up to a 10-hour battery life. Note: A 1-year warranty is included, although it's unclear who backs it.
