For in-store purchase only, Micro Center offers the Jawbone Mini Jambox Wireless Bluetooth Portable Speaker in Black for $19.99. That's tied with our April mention as the lowest price we've seen for this speaker. (It's also the best deal for any color now by $9.)

Features include Bluetooth 4.0, a microphone, 3.5mm auxiliary input, aluminum body, and rechargeable Li-ion battery with up to 10 hours of playback per charge.
