MissionFish
Founded in 1999, MissionFish is the partner charity of eBay, which runs auction and shopping websites in 30 countries. Through MissionFish, eBay users are able to donate to registered nonprofit organisations when they buy and sell through the eBay.com and eBay.co.uk sites. The programmes are called eBay Giving Works and eBay for Charity, respectively.
In June 2008, eBay announced that its global user base, through eBay Giving Works and eBay for Charity, had raised over $150M for good causes from listings created around the world.
