I usually don't advertise anything here but I like this idea so much that I want to share it:
One of my contacts has just set up a business 'gifts with meaning' where 50% of the sales will be donated to Australian charities.
He has started with Christmas Cards :-)
So just in case you want to send out cards, have a look:
http://www.giftswithmeaning.com.au
I myself send out personalised handwritten cards to my clients.
Cheers
