Walmart along with its partner Wing, is expanding its drone delivery network to seven new major metro areas, including San Diego.

Wing drones can fly at up to 60 mph and use a tether to lower packages directly into a yard or driveway, according to company’s website.

Other cities included in the expansion are Memphis, New Orleans, Philadelphia, Phoenix, San Francisco Bay Area and Salt Lake City. 

It is unclear exactly when the drone service will be available to costumers in San Diego. The companies said they plan to meet with local leaders and community members to share more about the delivery system.

The service is already available for Walmart costumers in Dallas-Fort Worth, Metro Atlanta, and Greater Houston.
