The United States Postal Service provides reliable and affordable delivery to every address. Customer experiences vary. Some find the local post office friendly and clean with reasonable prices and good parking, though supplies like tape may not always be available. Service is praised by some for secure delivery from dedicated staff, who are noted as the main reason for continuing to use USPS. Others express strong dissatisfaction with the service overall. The USPS manages many retail locations and delivers a large portion of the world's mail.
