Amazon.com recently announced a new social initiative called AmazonSmile.
The idea of the program is that 0.5% of all your purchases from Amazon will go to a charity of your choosing.
All you need to do to participate is to go to smile.amazon.com instead of Amazon.com

PS. The small problem with this idea is that you have to remember to login at smile.amazon.com before shopping for it to work. This Chrome extension that I just installed, automatically redirects you:
