Q: In App purchase for Charities

Has anyone ever managed to get apple to "give-up" its 30% cut of in app sales to charities??? im making a app that will have the totality of its revenue reverted to charities, so i was wondering if apple has ever show itself willing to cooperate... I was thinking, that if it was not up to not charge the 30% on every sale, it was willing to revert it to charity donation... to any charity...
