This is not the first time I have been advertising the Charities Aid Foundation (CAF) as a way of giving to charity, but I do think it's a good idea. You set up an account with them and pay in £10 per month or more. If you're eligible for Gift Aid, they claim it and add it to your account. They take off a small amount for admin (less than the Gift Aid) and you can then decide where to put the money. You can do it by the card or cheques they send you or online (the website is not the most efficient, but if you're not in a hurry it works). The best thing ( I think) is that you can donate anonymously, so you do not get endless appeals for yet more money. We've done it for years and can change charities as and when we want, or respond to special appeals, and no follow-up!
Eglantine21, what is wrong with giving to charities which have helped you? At least you know what the money is being used for, and that people can actually benefit from it, and I don't think to call it 'self-focused' is fair. You are giving something back.
