For in-store purchase only, Micro Center offers the Jawbone Mini Jambox Wireless Bluetooth Portable Speaker in Black for $19.99. (You must make your purchase in-store; however, you can use the above link to check stock levels at your local store.) That's tied with our February mention as the lowest price we've seen for this speaker. (It's also the best deal for any color now by $13.)
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.
