Tax and VAT.
This store will not charge VAT (Tax) if your shipping address is outside of the UK and European Union (eg: USA, Japan) or if you are located within the European Union but outside of the United Kindgom and you supply a valid VAT registration number (eg: The Netherlands, Germany). If your order shows VAT (Tax) and it shouldn't then you are probably not logged in - the VAT (Tax) will be removed before you conclude your purchase and the final Order Confirmation screen will display the correct amount (without VAT / Tax).
