postal service flat rate

postal service flat rate refers to a shipping option offered by USPS that allows customers to ship packages for a fixed fee, regardless of weight or destination within the U.S. USPS Flat Rate services include options for Priority Mail and Priority Mail Express, with various box sizes available. This can be an economical choice for shipping heavier items, as the cost is determined by the size of the box rather than the weight. USPS Flat Rate services are particularly useful for businesses looking to streamline their shipping costs.
