Payment here is by PayPal which will also process your credit card if you choose.
You can pay by check or PayPal.
You can now select auto renewal for memberships. Just choose the Member Recurring or Associate Recurring. The fees are the same. But it will help you to remember when the time comes.
A recurring payment will happen 365 days from when you first pay that way. If you choose to discontinue that, your membership would end the end of that year.
