We typically use USPS, UPS, or FedEx for delivery. Unfortunately, there is no way to exclusively choose which carrier we use for specific customers.
However, because most of the time the final delivery is made by USPS, we recommend using whichever address USPS uses to deliver to you.
If you have a PO Box and a physical address with the same city, state, and zip code, you can put both addresses (see the example below).
Address Line 1: PO Box 9999
Address Line 2: 123 Main St.
City: Cary
State: NC
Zip: 12345
If you have any issues with your package being delivered, please reach out to our support team here.
