For the next 2 months (now through the end of March 2010) I'm going to donate 80% of my profits from selling stuff to Doctors Without Borders to help them with their work in Haiti. This goes for merchandise for my comic Abby and Norma, books of my comic Abby and Norma, and my handmade jewelry as well.
If I could donate proceeds from my book Born on the Wrong Planet, I would, but it's professionally published and I don't get my next royalty check for a while, so I can't run a 2-month campaign for that. When I do get it, though, I'll probably use some of it for charitable purposes, too. I'm just that kind of person.
