None yet, which is unusual.
We send a lot, since many friends are far-flung. I had posted all my overseas cards by 30th Nov, and all the UK ones by 2nd Dec. One job out of the way - we will be a very big family party this year in a rental far from home so I have plenty of other stuff to do and think of, plus other family visiting in a few days.
I know two couples who have stopped sending cards, which I can well understand if money is tight. However these people are all very comfortably off so I suspect they just CBA. One of them said they would be donating the money to charity instead, fair enough, but these are the sort of people who could easily do both and not even miss it. Still, their choice.
Dh hates doing the relatively few he HAS to do, and puts it off as long as possible, so I suspect there's a bit of that involved.
