We just emptied our mailbox: it is now January 18, 2017. The mailbox was last emptied yesterday. There is a large card in three languages announcing the Golden Rooster Collection, in celebration of Chinese New Year. The unveiling took place on January 9, 2017. The card states that if you bring it to the celebration at 11:30 am on that day you will receive a FREE Day of Issue Collector Envelope (limit 500).
I know that the bad weather here has been hampering some mail deliveries. But to get this particular mailpiece nine days after the advertised event does seem to mark a new level of incompetence.
