John, could this be dealt with by offering the check box offered by the OP, and also another check box that says something like "I decline making a gift at this time, but please enter me in the raffle drawing". I doubt anyone would choose that, but by putting it out there would that be enough to please the IRS do you think??
Thanks to the OP – this is a REALLLY good question! J -Carol
