When you no longer want to offer a credit pack for sale, you can simply disable it. This will hide this from the list of available credit packs to buy for both users and staff processing sales.
This makes it easier to manage your credit packs by hiding the ones you don't need anymore.
Disabling can be undone by re-enabling the credit pack at any time.

To disable a credit pack:
Go to Settings > Credits and select either Class Packs or Appointment Packs

Select the Show Disabled checkbox (in the top right).
Find the appropriate credit pack and select Enable and confirm.
