If your credit card company is showing you a paid amount higher than what you were shown during the checkout process, then what you are seeing are additional fees the credit card company is adding as part of a currency conversion process.
Currency conversion fees are individually established by your credit card company. Scuf Gaming does not control if these fees are added to a transaction, or the amounts imposed.
To understand the possible impact of any fees prior to purchase, please reach out to your credit card company directly.
