Maybe you want to have a look at this U2 auction for the Tsunami hit people.

If you don't have that much cash, you can donate what you can afford here that is if your based in the UK. If your in the USA you can donate from a number of sites listed here.

If you live in another part of the world, please feel free to add a link for your country! If I get any links for other countries, I will repost this enty tomorrow with those links.
