A Letter from the North Pole

I've seen numerous resources for getting Santa letters...in an effort to compile:

"Google 'letter from Santa' and you'll find many sites selling customized letters. But few people know that the U.S. Post office can help too. Write a letter as if you were Santa Claus. Put it in a stamped envelope addressed to your child. Mail that by December 15 in a stamped, larger envelope to North Pole Holiday Cancellation, Postmaster, 4141 Postmark Dr., Anchorage, AK 99530-9998. Your letter will arrive with a "North Pole" postmark!"
