Why is this bill so expensive, what is the $78, I have never used it.

I'm not sure, but open a ticket if you haven't already. We'd be happy to double check your recent invoice.

We do continue to charge for Linodes that are powered off as they still have resources reserved, and are able to be booted up at any time.

If you no longer need a Linode you can remove it by using the blue "Remove" link on the right side of the "Linodes" tab in the Linode Manager.

If you're using the Cloud Manager, click on the Linode then the "Settings" tab for that Linode. Scroll to the bottom of the page and click on "Delete Linode" to bring up the "Delete" button.
