Amazon buy shipping is likely the most used carrier integration on the ShipStation platform. UPS Ground saver is the cheapest service provided by amazon buy shipping and was added all the way back on May 8th 2024. It is now August. It is ridiculous that it isn't available in ShipStation still. When contacting ShipStation I was given no other reason than that it is "Confidential". It is as simple as adding a new service to the existing configuration. Seems shady that it is "Confidential" and I suspect that it hasnt been added to direct more traffic to ShipStations own UPS Ground Saver Service.
Add the service.
