Upgrading a Subscription
If you've purchased a Blogger or Publisher license for AdSanity you can upgrade your annual subscription at any time. We options to pay the difference between your existing license and the license you'd like to upgrade to. This is accessed under the Purchase History in the My Account menu.

You'll then see the licenses available to you and can "View Upgrades" for the license associated with your subscription. The other licenses listed are for the Basic Add-Ons that are available at no cost with AdSanity or any Pro Add-Ons that you've purchased.
Finally you can select the upgrade that you'd like and complete your transaction.
