4 metro-Phoenix Walmarts now offer drone delivery

How it works: Place your order on the DroneUp website. More than 10,000 Walmart items are available, including fragile things like eggs.

• There's no order minimum and delivery is $3.99.
• Flight engineers guide the drone to your home and lower your package via a cable from 80 feet above the ground.
• The service is available from 8am to 8pm.

Details: Try it if you live near these Walmart locations:

• 21655 N. Lake Pleasant Parkway, Peoria 85382
• 7975 W. Peoria Ave., Peoria 85345
• 18551 N. 83rd Ave., Glendale 85308
• 5845 W. Bell Road, Glendale 85308

Zoom out: Walmart will offer the service from 34 stores in 23 cities nationwide by the end of the year.

• This will be the first large-scale drone delivery operation in the United States, Axios' Joann Muller reported.

The intrigue: Walmart and DroneUp will offset the cost of delivery with revenue from other drone-related services, such as insurance inspections, emergency response and construction oversight.

• For example, a local construction agency could work with DroneUp to monitor onsite job progress through aerial photography.
• Those other services will help the entire drone industry by gathering more flight data.
