I just wanted to post this again this year. Every year I write both of my kids a letter from Santa and through the North Pole Christmas Cancellation Program I mail the letters in a bigger envelope to the postmaster at North Pole Alaska and then they cancel the letters and send them back to my kids.

They get so excited to get mail, and when I point out it's from the North Pole they get really excited. It's so cute and only costs a couple of stamps. Chat Icon

ETA: In the link they list a bunch of holiday sounding towns that will do this for you, it's not just North Pole.
