I also got most of my Christmas cards into the mail today. I've been seriously trimming back the list over the years for cost reasons. And this year I finally worked through the last of many years' purchases of railroad-themed cards that I'd been buying for years until I decided that the I didn't fancy sending out more than 70 cards every December.
In this case, I expect I've waited too long and that quite a few cards won't arrive until the week after Christmas, particularly the ones going outside the USA. If I'd been more with it, I would have had cards with me for hand-delivery at SMOFCon and saved some postage.
