I've set up one product so far and managed to decipher your convoluted instructions on setting the shipping costs and so in the shipping calculator I have set teh Domestic box to say 1 and the International to say 2.4. I want my shipping charge for domestic to be $5 and the international to be $12...so in the product configuration in the shipping options I have specified weight in ounces to be 5.00.
So when I go tot he site and add an item to my cart and select United States and enter a zip code - a shipping cost of $5 is added to the cart. But when I select United Kingdom(Great Britain) and update the cart, no shipping cost is added....why not?
