As one of its daily deals, Best Buy offers the UE Roll 360 Wireless Bluetooth Speaker in five colors (Black pictured) for $49.99 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 low by $15.) It features a 65-foot range, 2" driver, dual 0.75" tweeters, rechargeable battery, and is waterproof. Deal ends today.
