So far, I've donated about 2 quid to the RBL when I got a poppy. If I give to charities, it's in a collection tin for animal rescue.
I get turned off charities that give bombs and more ammo and a renovation of the president's palace build water supplies for villages in Africa, that are destroyed a few weeks later during a raid by rebel forces. I suppose that puts me at the "Lower than snake's belly" dept of the donation club. Oh well.
