We ship globally with very few exceptions. You can check the specific address during the check-out process, if the delivery address is recognised we are able to ship to that location.
Shipping costs/ postage is calculated per order (based on things like weight, size and the shipping option you have selected - ie Standard or Express), once you have entered items into your basket and have proceeded through the check-out process the exact costs will be calculated for you.
For the most cost-effective shipping calculation, check the store location to the country you're shipping to (ie you live in Spain but shipping to the US, select the US store).
