This is definitely cool! GoodSearch is a service that utilizes Yahoo's search engine to earn money for charity. There are hundreds of charities already in their database, but if your favorite is not there, you can easily submit it.
For each standard search, your charity can earn about US$0.01. I know it doesn't sound like much, but if the supporters of that organization use GoodSearch regularly, it can easily add up to a significant amount.
They also have a service they call GoodShop, accessed through a link on the GoodSearch home page, through which you can earn even more money for your charity. They have many popular online shopping sites in many categories, such as eBay, Walmart, Target, and Amazon.
Each will donate a portion of the sale, up to several percent in some cases, to your charity. And it costs you nothing!
