FedEx requires the buyer to be present to sign for the package and provide proof of age in order upon delivery of the package. It is the buyer's responsibility to arrange for the acceptance of the package. We do not ship to a PO Box. We can ship to your place of business if you prefer. If the package is returned to us from FedEx because it could not be delivered, the buyer may pay for shipping again, and we will attempt to ship the item(s) again.
