I'd offer two comments. One is that for charities that have recurring monthly donations we offer a special rate that we call a recurring payments rate. The second comment is that cards deliver tremendous value to charities. They allow them to extend their reach and generate cost efficiencies.
I reflect back two weeks to my son's fourth birthday party. We decided we didn't want toys. We decided to set up a giving program at SickKids hospital. It wouldn't have been possible without the existence of credit cards. The $700 of donations that he generated through that program would possibly not have ended up with SickKids had we not had cards.
