USPS is the biggest, most favored carrier in the U.S. Operating exclusively within the country, USPS relies on other postal services for last-mile deliveries when shipping internationally. The company offers the lowest prices among its competitors while maintaining quality services. USPS may be the perfect carrier for low-cost, non-urgent deliveries, as it is among the slowest postal services with no precise time frames for delivering parcels and big packages.
