As currency exchange rates fluctuate on a daily basis, the conversion to local currency will be made by your bank on the day of purchase. Check out today's currency conversion rates using a search engine and an appropriate currency conversion tool, though do bear in mind that the rates displayed may be subject to change before your bank processes your transaction.


All displayed prices exclude TAX.

Any orders placed within the UK will have VAT/TAX added during the checkout. 

Note that, while purchases made from outside of the UK are not subject to VAT, such shipments can instead be subject to alternative import duties and/or taxes depending on the laws of the destination country. These are outside of our control, so you should contact your country's customs authority for more information if you wish to know what sort of costs you may be liable to pay in order to receive your order. Any such import duty/taxes/fees are not payable to us during the checkout process but will usually be paid to the company that delivers your order.
