Adding more codes

To add more codes to an existing discount set, you can easily do so from the dashboard. First, find the discount set in the list. You can change the list's sorting behavior and click through pages with the actions below the list. Once you've found the discount set you'd like to add codes to, simply hover over the row and click the Add codes action that appears. You will then be able to specify how you would like to add codes and the form will remember your last used settings.

If you need to change the details of the discount itself or would like to export all of the codes for a particular discount, you may do so from the  discount details page within the Shopify admin through the "Go to discount" action on each discount set.
