How do I add/subtract add-on credits?
Go to the subscription page and note the list of Associated Add-on Subscriptions at bottom of page. Each line is a different add-on purchase, to the right is a xx/xx notation. The first number is deliveries made/the second number is paid deliveries. Click on the numbers to add or subtract add-on credits.
IMPORTANT NOTE: write the memo first. Once you click the add/subtract deliveries button the change is saved. Also note--unit is the same as count.
