All our prices are in Euros and include all sales taxes. We only sell at our advertised prices. As permitted by EU regulations, we operate tax-free exports: customers outside the EU are not charged sales tax (7% on printed matter and 19% on all other items). We always try to avoid price changes. If we have to change a price due to fiscal situations, exchange rates or other external influences, then we immediately update that price on our webshop, the webshop price is always the prevailing price.
