Goldstar_Tech via eBay offers the open-box Amazon Tap for $88.98 with free shipping. That's $31 under the lowest total price we could find for a new model. (For further comparison, we saw a new one for $1 more in December.) It can play music, provide information, read the news, set alarms, and control smart home devices via button-activated voice control (with the same Alexa Voice Service used in the Echo). It features a single microphone, dual 1.5" drivers, dual passive radiators, WiFi, Bluetooth, and 360° omnidirectional audio.
