Additional #fees such as bank fees or credit card fees may be applied depending on the currency of the event and depending on your bank / credit card supplier.
It is also possible that the difference comes from the exchange rate on the day of the transaction, if your account has a different currency than the official event's currency.
We invite you to check with your bank first, and then contact your event's registration team if more details are needed.
All costs are to be borne by the ordering customer.
