    Go there

    Add one in your basket, go to your basket and select the right shipping method... you'll have all the answers.

    Don't forget the Currency conversion... ready to jump on your chair?

    It's not a bug, it's a random feature.
    There's no problem, only learning opportunities.

    Similar to how most US websites will not show anyone in the outside world the cost in their local currency then!!!

    At least Crownhill are prepared to ship all over the world. Many US websites wont do international shipping

    If it still gives the total cost in Pounds Sterling (GBP) then take a trip to http://www.xe.com/ucc put that value in the text box, select convert British Pounds to US Dollars and you will get the value in dollars.

    Dont forget that it will cost you slightly more than the true pound/dollar rate because your credit card company will have an exchange rate weighted in their favour and will probably also charge you conversion fee.
