Belk offers the 2nd-generation Amazon Echo Dot Bluetooth Speaker in Black for $19.99. Opt for in-store pickup where available to dodge the $8.95 shipping charge. That's tied with our December mention and the lowest price we could find by $7. It features Alexa voice control, 802.11n dual-band wireless, Bluetooth, and a 3.5mm audio output. Note: A 90-day Amazon warranty applies.
