Beware - embedded giving is not always what it seems. Particularly in the case of iGive - a site that lets you designate "your favorite cause" as the recipient of funds donated by merchants when you make purchases. Most of the causes run along the line of "my trip to Hawaii," or "Mama needs a new pair of shoes." The site explicitly states "Any cause in the U.S. or Canada qualifies - and 501(c)3 nonprofit status is not required." So go ahead, shop on. Just don't consider it charity. And don't try to write it off.
