We have only had 3 cards so far this year. None were charity (tho one was M&S, which has some blurb about recycling and the Forestry Commission).
One had a computer generated label - ok, I can live with that, just about. But inside was printed "Merry Christmas and lots of love from The Smith-Jones" (pseudonym). Our names were handwritten, but no other signature etc.
Now, in my book, cards MUST be charity, and should be brought from a proper charity, eg a charity shop or stall or via mail order, not those boxes you get in WHS which say "20p of this £4.99 will go to 200 different charities".
And you should also write a personal signature and preferably message. Round robins are a whole other subject...
AIBU?!
