How to Cancel an Online Magazine Subscription for Nookby Micah McDunnigan
You can't get refunds for online magazines you've already received through your Nook, but you can avoid paying future renewal charges and get a prorated refund for issues you haven't yet received by canceling your subscription. You can do this online through the account management portal on the Barnes & Noble website.
Go to the Barnes & Noble website and log in to your account.
Select "Manage Account" from the My Account menu at the top of the page.
Scroll down to the Digital Content section and then click "Manage Your NOOK Subscriptions."
Locate the title of the subscribed magazine you want to cancel and click "Cancel Subscription" next to the title. Confirm your cancellation request in the dialog box that pops up.
