chewbacca same here! not sent Cards since dh passed just over 3 yrs ago, I have no longing to send them or receive them any more. I normally put a donation in to a charity or buy equivalent in food and drop it in the food bank trolley.
I am really not fussed about receiving any cards (still like birthday cards)
If I do get them they just sit in a pile, I have said to all I dont "do" Christmas cards any more, sbut they still seem to send me them...think they feel bit bad if they don't but I would rather them give a donation or something..
