Using this set up, you can add a charge to be applied to any orders that are shipping on a 'Collect' shipping term. This is to cover the loss of not being able to mark up on our carriers charges.
Configuring this page can be done in :
Advanced / Administration / Configure additional Charges - markups, cod charges.
In the field marked 'Collect Shipment Charge (per carton)' enter the desired charge to be applied to all orders that have a Shipping term that has been flagged as 'Collect'. This charge will applied for each carton on the order.
Shipping terms can be set to be 'Collect' or not in the Manage Shipping Terms screen.
