Can I Add a 6th Device to My Subscription and At What Cost?

I have a 5 device Norton 360 Deluxe subscription. I recently purchased a 6th device that needs protection. Can I add a 6th device to my Norton 360 Deluxe subscription for an additional (incremental) annual cost or must I purchase a new subscription that provides protection for more than 5 devices. In short, I don't need to protect 10, 25 or 50 devices, just 6. Thanks in advance for any replies.

Thank you.

There is no way to incrementally increase your device count as you are requesting. The next product level would be a 10 device subscription. You can contact Norton Support and have them help you with the upgrade to the newer version.   www.norton.com/contactcs
