There is no "cancellation" for Hulu Store as Hulu Store offers you pay per view service you pay as you purchase/rent the titles you like.
You can delete payment information unless you use it for Hulu monthly subscription.
You can delete it with the following steps:
- Access to the account page.
- If you are not logged in, you will see a login screen. Please log in with the e-mail address and the password.
- If you are asked to select a profile, please select the one on the most left or an owner profile.
- If you are asked to enter the password again, enter the password and select [Next].
- Select [Delete] on the right hand at the bottom of the "Service Usage."
- Select [Delete] to confirm.
- When it is complete, you go back to the account page.
