Selecting Hold for Pickup is something that is offered by eShipper but isn't available in ShipStation, and is extremely useful to us as many of our customers require this service.
Currently we have to go back to eShipper to ship these packages, we would much rather use ShipStation.
Looks like this can be an option:
When shipping packages, use the Hold for PickUp option, and the recipients can collect the package at their local Post Office™.
Please integrate this feature into ShipStation with USPS as it would cut down on Fraud and Friendly Fraud.
