With the new USPS Ground Advantage shipping service we are now getting orders for this service that are more than the insurance included with it and it requires going to the post office and standing in line to add additional insurance which we do not have time to do. - We need the ability to disable individual shipping services from appearing on the shopping cart and checkout pages for orders with a subtotal that is over a certain amount. Please see the attached image for a suggestion on how to implement this.
