At Amazon, if you pre-order the new Amazon Echo Plus, you'll also get a free Philips Hue Smart Bulb. They will ship on 10/31. The new Echo Plus features a built-in smart home hub that works with ZigBee (a wireless smart home protocol) devices from brands like Philips, GE, and more. This relieves you from having to buy a separate hub. The addition of the bulb saves you about $15. This smart speaker also features a new speaker design with Dolby processing and, of course, the Alexa digital assistant. Sales tax is charged in most states.
