For its members only, Costco offers the Ring WiFi Video Doorbell in Satin Nickel, model no. 88RG000FC01, bundled with the Ring Wireless Doorbell Chime, model no. 88CH000FC000, for $179.99 with free shipping. (You must sign-in to your Costco account to see this price.) That's $38 under the lowest total price we could find for these items purchased separately elsewhere. (For further comparison, we saw the doorbell alone in another color for $169 in December.) The weather-resistant doorbell chimes on all your connected devices, including smartphones, when you have a visitor, allowing you to answer your door from anywhere. Features include a 720p camera with night vision, motion detection, built-in Li-ion rechargeable battery, and up to a year of run-time between charging. The chime connects to any standard wall outlet and features adjustable volume controls.
