How To Delete A Shipping Method
Shipping methods can be deleted at any time, and without affecting the Scenario they're assigned to. However, you will need to have at least one shipping method assigned to a Scenario for customers to be able to check out.
Deleting a shipping method is permanent and cannot be undone.
1. Click Shipping on the sidebar menu, then select Scenarios from the drop-down list.
2. Click Edit beside the Scenario with a shipping method you wish to delete.
3. Scroll down to the 'Shipping rates and services' section, then click Edit beside the shipping method you wish to delete.
4. Scroll to the bottom of the page, then click the Delete button.
