Haha, see I just read the first post but exactly what I assumed.Remember, claiming that you're "donating X to Y Charity" - even with a disclaimer - requires regulatory confirmation from the charity.
If the charity is real close to you, you have absolutely no need to even make the above post. Just donate, claim deductibles and move on.
If you truly want to do charity there is no need to talk about it. For obvious reasons, charities do not want to be used as bait for people claiming I will donate x% of sales to charity X. Now for smaller ones, likely they do not care, but when you look at the big ones (WWP being one of them) they will NOT collaborate with you on this, unless (and that is theoretical) your donations would be worth it to vet you.
