The currency displayed to visitors is determined by visitor location, while logged in users' currency will display as per their billing country's currency (GBP, USD, EUR). Logged in users can change their billing address via 'My Account' (link). Final billing currency can be reviewed during the 'Order preview' stage of the checkout process.

You will be asked to enter an order number or reference during the 'Payment method' stage of the checkout process. Billing and shipping address will also be required. Upon completion of your order, someone from the Ricardo team will be in touch to confirm your details and issue an invoice.
