Amazon (full disclosure, I work there, but not on this project) has a new version of its website called Amazon Smile, where you can pick a charity and Amazon will donate 0.5% of your purchase price to them.
To donate to our favorite freeform radio station, go to
http://smile.amazon.com, search for WFMU, pick Auricle Communications from the search results and then make sure you always shop at smile.amazon.com instead of
www.amazon.com.
