On today's show I was talking about how to get your cards postmarked with "Christmas Island, Cape Breton" on your mailings this year. Here's the information I said I'd post:
Address and place the correct postage (or something called an international reply coupon.. I'm sure you could get more information on that from your post office) ON the actual card, insert the card into a larger envelope and send to:
Christmas Island Post Office
8499 Grand Narrows Hwy
Christmas Island NS B1T 1A0
You should do it soon, to ensure your stuff arrives at its destination in plenty of time.
And, more importantly, anything for me can be sent care of this station. :)
