I used Shutterfly when I sent out Claire's birth announcements and they turned out great. The cards were easy to make, and there were lots of options to choose from. It took me forever to pick a design for her announcement, and I can see that choosing a Christmas card from all the options available won't be any easier. I'm leaning toward a card with spots for multiple photos like this one. That way I don't have to choose just one Claire picture! If you still need holiday gifts for people Shutterfly has many great options like calendars, photo mugs or ornaments.
Disclosure: This post was written as part of a promotion for Shutterfly, which I really do love! For telling you about their holiday cards I will receive a code for 50 free cards.
