My best friend just bought a 2 million dollar home on the water. She has moved there from San Diego. Several friends have sent Christmas cards to her new address only to have them sent back undelivered saying insufficient address unable to forward! If the postal carrier is new? Fire them!


You have to send to PO Box. No mail service on the island.
