If you are charging for additional shipping methods like Special Delivery, Express delivery, etc., you can set up a shipping variation, which will charge extra on top of the shipping rate if selected. By default, the shipping variation is only displayed on the cart page if any of the items in the shopping cart have “Applied shipping” selected “Yes.”
To set up a shipping valuation, go to Shipping from WP Shop Cart’s main menu, select “Show shipping Variation”, and enter the variations in the shipping variation table.
Once the shipping variations are configured, it will appear on the Cart page like below.
Customers will be able to choose the variation they require from the “Shipping variation” drop down list.
