If you are renewing an existing subscription, just place an order through the store and select the option for renewal (instead of new subscription) on the billing/shipping information page during checkout.
Please note: your login (username and password) for our magazine sites – where you can read articles and other online content – is not connected to this store. You will need to register during the checkout process so we have your name and address for your subscription purchase.
