Amazon has organized a program for giving to the relief effort for the victims of the Haiti earthquake, the Mercy Corps. The links here will take you directly to the Amazon web page to make your donation, so you will be sure that any donations wind up in the proper hands. It's sad to say, but the scam sites are already being set up and scam emails are sure to be flooding our mailboxes soon, as they have with every disaster over the last few years. I would suggest you be wary of any donation efforts on individual web sites and stick with either the larger retailers who have set up donation campaigns for their customers or donate directly to the relief organizations, such as the Red Cross (just be careful to make sure you are on the correct websites and that a smaller organization really is involved; many are, but are government funded or collect in local churches, so may not have web donation efforts).
I've added a link to the Mercy Corps donation page at the top of the menu on the left side of the page and will leave it up as long as Amazon is accepting donations. Thank you for making a donation in this time of great need.
