The shipping cost rules require the customer to submit a country name and a ZIP/postal code before calculating the cost. However, the ZIP postal code validation seems screwy. Eg for the UK, ZA and NZ any none blank data seems to be accepted, for the US it seems that real validation is performed, however, and most importantly for me, all valid post codes are rejected for Australia..ie I cannot sell products for shipment to AU
I am in the process of testing these facilities before merging into our live site and so I am afraid that you will not be able to see this directly, but it is pretty simple to test off-line
