Do you know about the address-filters tag? If you're using Merchant Calcualtions you must use address-filters to specify restricted and allowed shipping areas. For example, if you set your address-filters to indicate that you only ship to the lower 48 states, and a buyer selects an address in Hawaii, the buyer will see a message indicating the seller does not ship to the location. The address-filters are evaluated before Google Checkout sends the merchant-calculation-callback request to your system- so it can save you server cycles or 3rd party shipping API calls.
You can continue to use the shipping-restrictions tag. But Google Checkout will only look at shipping-restrictions if the merchant-calculation-callback fails for any reason. Here's an XML snippet for a shipping method that ships to all 50 US States under normal circumstances. If the callback fails, however, this method will only ship to the lower 48 states for a price of $8.00

If you only use shipping-restrictions and Google Checkout receives your merchant-calculations-results, then the shipping-restrictions won't eve be evaluated. If you rely on Google Checkout to decide whether or not you ship to a given address, it is important that you use address-filters.
