Ethical Credit Cards
There are several affinity credit cards cards available which help to contribute to charitable causes. When you take out one these cards, there is often a one off payment made to the organisation of your choice. Whilst these amounts tend to be quite modest (£25 is a standard amount), the card company typically donates small amounts each time you spend money on the card - for example, a donation of 10p for every £50 spent is typical.
American Express have a "RED" card where 1% of what you spend will be donated to combating AIDS. For more information, try: www.joinred.com.
