USPS changes to shipping options | July 2023
Please note that effective July 9, 2023, the United States Post Office discontinued First Class Package Service, Retail Ground Service, and Parcel Select Service. These services are now rolled into a new service called Ground Advantage which is sometimes less expensive than Priority but slower (2 to 5 days).
In checkout you will typically see Priority Mail, Media Mail (when applicable) and Ground Advantage as shipping options. If you are most accustomed to selecting Retail Ground or other package services, Ground Advantage is the new name for those shipping options.
