I am not able to get all the rates to show in my store. ShipStation is showing the lowest rate for the shipment only. I can not figure out how to fix this and so far after weeks the S.S. support can not figure this out. I need UPS and USPS because some people have a P.O. box and UPS will not deliver to P.O. box and the SS software is not smart enough to figure this out. Also, some people want 2 day select or maybe overnight, these rates need to be an option for customers.
