My catalog host lives way out in the boonies in MT. Can she have her orders shipped to her P.O. Box?
No, you have to have a physical street address. FedEx should deliver it.
No, she can't. Have her check with her local post office, though. Our local office can accept UPS and FedEx deliveries. I believe she just needs to use her name c/o General Delivery, then the physical address of the post office.
