CALIFORNIA -- Postal employees will not accept boxes that are eligible for international flat rate delivery. Such as large video box code: 01096L.
BUT wait!!!! I showed them the IMM (International Mail Manual) exhibit: 232.2b very clearly states that is eligible AND USPS.com click & ship lists such box as FLAT RATE international and allows you to print the shipping label. STILL with all this evidence I talked to at least 7 postal employees and 2 supervisors and to the Santa Ana, CA service center and they had NO CLUE of what I was talking about!!!
