Walmart offers the Eco WorkChoice Indoor WiFi Tap Outlet in White, model no. CT-065W, for $19.20. Choose in-store pickup to avoid the $5.97 shipping fee. That's tied with our mention from a week ago, $5 off, and the lowest price we could find. This 7-day programmable tap outlet allows wireless on/off functionality and power consumption monitoring via the Eco Plugs app for iOS or Android.
