If its coming from the States, I would prepare myself for a shock when the courier arrives. This will take the form of a demand for import duty as its a county outside of the EU and carries a tariff.
My son found this out ordering Tshirts, he ordered 3 shirts for £70 (rock band T's only available in the US), then had to stump up another 18 quid in tax and courier delivery when they arrived. He now gets one at a time sent which falls under the limit for claiming tax.
