Which is cheaper FedEx UPS or USPS depends on several factors, such as the size, weight, and destination of the package. USPS is generally the most affordable option for smaller, lighter items, particularly with services like First-Class Mail and Priority Mail. For heavier packages, UPS and FedEx might offer better rates, especially for ground shipping. UPS and FedEx often provide faster delivery times, but they tend to be more expensive compared to USPS for standard services. To determine which carrier is cheaper for a specific shipment, it’s recommended to compare rates using each carrier’s shipping calculator based on the package details and delivery timeframes.
