This WiFi-connected drop box will lock once a package is placed inside it. If you're expecting multiple packages, you can create a PIN and include it on your package address for the delivery person to use. Using the companion app, you'll receive push notifications when packages arrive, and since the drop box has a 1080p camera and two-way audio, you'll be able to communicate with your delivery person. Price drops from $399.99 to $159.99. Shipping is free.
