Dig this, from author and historian Glenn Stout:

Let’s try to do some good here. I don’t have to tell you what is happening in Haiti and how they are in need of everything, but I was looking around my office the other day and came up with an idea that might give a small measure of help.

Here’s the deal – I have extra copies of some of my books (see list below). In exchange for a donation to the reputable charity of your choice, I’ll send you copy of the book signed by me.
