Amazon plans to expand its drone delivery service to nearly 500 US cities by the end of the year. 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.

Further details on Amazon's plan and its impact on the delivery market are available from the source, including the company's ongoing competition with Walmart to provide fast delivery times.
