FedEx Ground Economy (formerly known as FedEx Smart Post) is a service from FedEx that uses the United States Postal Service (USPS) for final delivery of low-weight packages. It is a cost-effective shipping method that allows us to offer free shipping on a wide range of product designs. We use FedEx Ground Economy in certain instances to ship to the continental U.S., Alaska and Hawaii. For more information, please see the FedEx Ground Economy website.
