which is cheaper to mail packages

which is cheaper to mail packages depends on the size, weight, and destination of the package. USPS is generally considered the most affordable option for smaller, lighter packages, especially for domestic shipments. For larger or heavier items, UPS and FedEx may provide better value, but their rates are typically higher than USPS for basic services. To find the cheapest shipping option, it’s recommended to compare rates from different carriers based on the package’s specific details using online calculators or shipping software.
