The only way to pay for a subscription to "O, The Oprah Magazine" is via credit card, either directly through the magazine website or through Amazon's website. The credit cards taken through the two sites include Visa, MasterCard, American Express and Discover cards.
The subscription to the magazine is self-renewing. This means that if the customer fails to cancel before the new subscription period begins, their same payment information will be used and charged for a new term of service. The customers need to contact customer service at least 30 days before renewal to stop the auto renewal process. The renewal will also be at the current rate of the magazine, so the price customers sign up for at first may not be what they pay when they renew.
