ups ups surepost UPS SurePost is a service that combines the reliability of UPS for long-distance shipping with the affordability of USPS for final delivery. UPS handles the initial leg of the journey, while USPS delivers the package to the recipient’s address. This service is often used for smaller, lighter packages and offers cost savings compared to standard UPS Ground shipping. SurePost is typically slower than regular UPS services but offers an affordable alternative for non-urgent deliveries.
