Please note:
We use a donation platform (Zeffy) that doesn't charge us. Zeffy survives on tips from donors.  
When confirming your donation to us, you will have the option of giving a tip to Zeffy. 
Zeffy set the default at 10%, but you can adjust it to whatever feels comfortable even if it's zero. 
If you are so moved, an additional $1 per $25 donation basically covers their expenses.

Also, if you would prefer your gift to be physical books as opposed to ebooks, 
please add another $10 per book to your donation to cover printing and mailing costs. 
The physical book option is only for U.S. addresses.

Descriptions of the gift books appear on the Thank You Gifts page.
