They've had that option, as well as UPS, for a while now. Most free shipping goes that route. Most orders I get that go from FedEx or UPS to PO take up to a week after they get to the PO to get to me. Obviously they can't deliver it in that city, so really all you can do is wait or call that PO and ask. If you know the PO name/number you can look up their phone number.
