I'm running WooCommerce for a client. We have him setup with USPS for all shipping. I realize you can change the shipping defaults in plugin setup if you have more than one shipping option with different companies (IE, USPS, FedEx, and UPS).
My problem: We are only using USPS but have multiple shipping options within. I can't figure out how to change the default to be the cheapest available option. We are offering Express & Priority. It appears it doesn't matter what order you add the shipping options to the list.
Does anyone know a workaround for this? Your help would be greatly appreciated.
