As one of its daily deals, A4C offers the refurbished Amazon Echo Plus Voice-Controlled Speaker / Smart Home Hub in White or Black for $79.99 with free shipping. That's $30 under our May mention and the best price we've seen for it in any condition. (It's also $70 under the price of a new one at Amazon.) It can act as a smart home hub for devices compatible with Zigbee radio, including smart products from brands such as Philips Hue, GE, and Kwikset. Deal ends today.

Note: A 90-day A4C warranty applies.
