Amazon has announced a plan to expand its drone delivery service to nearly 500 US cities. This expansion will allow millions more people to receive smaller, lightweight packages by drone. The drones are capable of carrying packages up to 5 pounds and can deliver them in as fast as 30 minutes.

The plan is expected to increase competition between Amazon and Walmart for fast delivery times. Both companies use a combination of drones and drivers to deliver packages.

Further details on Amazon's drone delivery expansion are available, including the potential impact on the package delivery industry.
