Ask how you can help Santa bring something to others! In this season of giving, worthy causes are hoping for a last-minute contribution OR at least a piece of your gift-giving budget (if you buy gifts from people/organizations linked to worthy causes).
Heifer International; another year I helped rebuild New Orleans through donations to Habitat for Humanity. This year and last, I helped small-scale entrepreneurs through microloans via Kiva.
Many worthy causes are competing for us to play Santa through them. Nicholas Kristof of the New York Times suggests some that aren't well known but deserve consideration on your nonprofit donation list. Time magazine discusses a few that have good track records for putting donations to use.
Not sure which nonprofit to choose for your donations? Charity Navigator, among other sites, will help you figure out who does what and how efficiently the organizations use your money.
You still have a few more days to play Santa. What are you waiting for?
