JustGive.org Buttons is an add-on available to all users that allows you display a button on your site that your visitors can use to make donations to charity.

JustGive.org is a nonprofit service whose mission is to connect people with the charities and causes they care about and to increase overall giving. When your site visitors click the JustGive.org button on your page, they'll arrive on a JustGive.org page that will guide them through the donation process. The organization will deduct 3 percent of each donation to cover its transaction costs.
