Id like to donate money to a particular charity but I don have much spare cash. Ive seen charity credit cards, how do they work?
It will depend on which charity you want to donate to, but, in general, once you sign up for the card a donation is made by the card provider and then every time you use your card a percentage of the purchase price is sent to the charity at no cost to you. As with all credit cards you should check that the interest rate and other details suit you.
