Welcome to the alternate gateway for your membership payment.

Issues with payment through the membership application occasionally happen. This page is a manual payment option. It will not link to your account, and the payment won’t show up there; however,  it does not affect your membership status, which I have set up for one year.

Don’t hesitate to contact me with any questions or concerns.
