Walmart could be expanding its drone delivery service to St. Louis in the coming months, according to multiple reports. Drone company Wing is working with city officials in Manchester, Maplewood, St. Charles and Glen Carbon to set up launch sites. Last week, the drone delivery service kicked off in Apopka, Fla., marking Walmart’s first entry in the state. The drone delivery service will eventually be available at five Walmart locations in the Orlando region. At the beginning of the year, Wing said the plan was to expand Walmart’s drone delivery system to 150 additional locations in the coming year.
