Pick a site through which to renew. There are dozens of sites that offer subscriptions and renewal subscriptions to TV Guide. You can use the TV Guide site itself, or any of the others linked in Resources.
Enter your personal and payment info. Approve your purchase. Your subscription will continue uninterrupted.
To renew by mail, retrieve a subscription insert card from the last TV Guide you received. Fill out the relevant personal information, making sure to indicate that you are a current subscriber.
Indicate whether you will be paying by check or credit card, or whether you want the renewal to be billed to you. Fill out payment information if applicable.
If you are paying by check, put the check and the insert card in an envelope, address it to the magazine, stamp and send. If you are paying by credit card or requesting to be billed later, there is no need for postage--just fill out the card and send.
If you don't feel comfortable renewing online and can't find a subscription card, renew by phone. Call TV Guide Magazine Customer Service at (800) 866-1400. Be sure to have your mailing and payment info handy. A customer-service representative will take you through the renewal process.
