Here's how you can do it:
Individuals
Do you want to support a cause?
If you don’t see the cause you want to support, contact the organization and let them know.
If you want to support a specific project or member of the organization, make sure the organization lets us know.
If you want to receive support this way, let your sponsoring organization know about this opportunity.
If there’s no specific project or individual designated, we'll donate to the organization. This means the donation will most likely go into the organization’s general fund to be used as the organization’s leaders see fit. This isn’t a bad thing – it’s just something to be aware of in case you'd rather have the donation used for something in particular.
Now for the bad news: because we're making the donation, we get to deduct it as a donation, not the individuals who buy copies of the book.
