Because you are purchasing from a business based in the UK, the actual transaction will always take place in GB Pounds. To improve your shopping experience, we use a facility that dynamically references the latest exchange rates, and substitutes the displayed prices in real time.
The displayed currency conversions are approximate and should be used for informational purposes only. The actual transaction is still done using our store’s base currency during checkout with your card provider and/or PayPal automatically converting to your country's currency for banking purposes.
I hope this helps answer your question.
