We use WordPress and WooCommerce on our site and to calculate freight we use the Postcode Shipping plugin. Our freight has 3 values (great São Paulo, SP interior and neighboring cities) and is fixed only charged per order and not per product.
The issue of having 3 fixed values for freight in part is already resolved. But when a customer informs a zip code that there is no freight medium available, it appears Free , how do I remove the word "Free"? I already researched the plugin file but could not.
