The Satanic Missionary Society is now an officially registered non-profit corporation in the State of Washington.
It seems the clerk at the state office was a little nervous when reviewing our application, and entered the PO Box incorrectly in their system, so we never received any mail. We've filed a form to correct the address, but this means you should be able to write checks payable to "Satanic Missionary Society" soon!
Please do not mail correspondence to PO Box 11754. The correct address is PO Box 11753. Hail Satan!
