Affinity credit cards not benefitting charities as much as you'd think

Affinity cards, credit cards that carry the logo of a charity you support, may make you feel good, but are you really helping out the charity? You are, but you could end up giving much more by choosing other options.

"Affinity cards tug on our heartstrings. We all have causes we like to support. But in most cases, an affinity card is not the wisest financial way to support the organization," Bill Hardekopf, CEO of LowCards.com, told me by e-mail interview.
