USPS Flat Rate Box

The USPS Flat Rate Box is a shipping option that allows you to send packages of varying sizes for a fixed price, regardless of weight or distance, as long as the item fits inside the box. These boxes are available in different sizes and are pre-priced, making shipping cost planning easier. They are suitable for sending heavier items or multiple products economically, especially when shipping internationally or over long distances. You can purchase the boxes at USPS locations or online, and they are a convenient and cost-effective way to mail items without needing to weigh or calculate postage each time.
