I have heard about this on a few different blogs and think its a great way to support relief efforts in Haiti. As a crafter, you can donate items to be sold on etsy, as a shopper (me!), you can support their efforts by purchasing something from the store! All proceeds will go to Doctors Without Borders in Haiti. I have my eye on a little something, but I think I will use it as a gift, so I can't tell :)
One more place to donate that you may not have initially thought of, Catholic Relief Services. They are already on the ground in Haiti distributing food and supplies. I felt very comfortable giving to CRS, 93% of the money they spend goes directly to help the poor overseas. They also meet all 20 of the strict Charity Standards set by the Better Business Burea's charity rating arm, the Wise Giving Alliance. You can visit them here.
