I have set up 2 shipping methods: one deals with the weight, the other with the volume.
When a product is added to the cart, the correct method and shipping fee does get applied depending on whether I've added the weight or volume information to that product's information page.
But both shipping methods are displayed on the checkout page and the customer can choose the method they want to apply and select the less expensive method.
I don't want to give the customer this choice because the shipping fee for some products will depend on the weight and for others on the volume.
How can I remove this list under the words "Shipping Method" at the top of the checkout page?
