I had never heard of smile.amazon.com, but its a thing. Basically just start at that url and all your Amazon purchases will give a small cut (0.5% I believe) to a charity of your choice. For example, search for 'Keeping Pace With Multiple Miracles Inc' and set that as your charity. If you want to go all out, check out www.smilealways.io. Its a Chrome plugin to always change amazon links to smile.amazon links. cool.
