As one of its daily deals, Amazon offers the 2nd-Generation Amazon Echo Dot in Black or White for $39.99 with free shipping. That's $4 under our mention from last week and the lowest price we've seen without needing to order via Alexa. (It's also the best deal we could find today by $6.) It features Alexa voice control, 802.11n dual-band wireless, Bluetooth, and a 3.5mm audio output. Deal ends today.
