If your GoComics Premium membership currently shows a "Free" status, it means that your Premium benefits have expired.
To provide new payment information and resume benefits such as the daily comics email and ad-free comics viewing, please log in to your expired account.
Next, you may either click on the Person icon in the top right corner and select "Free Trial" from the drop-down menu (this will appear only if your account qualifies for the trial), or:
Click on "My Account," scroll down to "Subscriptions," and select "Try Free Trial" or "Change Billing Info" (if your account qualifies). *Both options will provide the same result of renewal.
