Yes, our shipping zones are fine and have been working great for months except for in the case of this one recent order for this product.
Ordering different products to the same postcode work fine and ordering the same product to a different postcode works fine it just seems to be something about this combination of product and postcode that is causing an issue.
I have already had a ticket open with WooCommerce who have looked in to all the shipping settings and other stuff with me and they have referred me to come to you as the plugin developers because they said the problem was not with my WooCommerce setup and is caused by the plugin.
