Yes but Jules with no disrespect to FIG, giving "a contribution" is not what you describe as "clear from the start". Saying something like "25% of the proceeds will go to FIG" is clear. This is where this all falls down. If I am buying women's clothes (and I might, who knows what I get up to) at a FIG charity event, I deserve to know that from the £20 I spent, are FIG getting a tenner, a fiver, 28.3p or will it be nothing specific, just a bung at the end once the private seller has lined their pocket. People have an absolute right to know exactly what they have contributed to the charitable cause will end up with the charitable cause and not an individuals wallet. If a charity can't give that information before the event, it really should be considering whether to be involved with the event at all.
