Each ASHM membership is valid for one year. If you select a one-time payment for your membership, your membership will end one year after your payment date. You will be sent a reminder via email one month before your membership ends.
If you select an annual subscription, your membership will automatically renew one year after your initial sign-up date. At this point, your nominated payment method will be charged the relevant membership fee. You will be reminded via email one month before you are charged. You can cancel your auto-renewal at any time on the subscriptions page.
