If you're hoping to get letters postmarked from the North Pole, you better hurry. Today is the last day.
Holiday letters and cards sent out by Monday, December 10 will be stamped with "Santa" as the sender.
To take advantage, you need to place the card or letter from Santa in its envelope with First Class Mail stamps. You should also have the return address as "Santa, North Pole." Place the card in a larger envelope with the correct postage and address that to:
North Pole Postmark Postmaster
4141 Postmark Drive
Anchorage, AK 99530
