American Express is putting its money where the volunteers are. Through its newly created Members Project, cardholders can receive Membership Rewards Bonus Points for choosing volunteer opportunities listed on the AmEx website and can use their credit card to donate to their choice among thousands of nonprofits. And anyone accessing the website can vote weekly to decide which five charities will receive a total of $1 million. The slogan is "Take Charge"...sounds like American Express is showing the way.
