The website will automatically calculate the shipping costs based on your location and the total weight of your order. You can see the shipping cost on the cart page before you go to checkout or have to pay (although please note that a default shipping price may be displayed until you have entered your address details and moved on to the next section).
In some cases - particularly if you order many items at the same time - it may be best to email or phone with your order rather than using the website shop so we can double check the best possible shipping cost.
