Does your purchase total differ from the one you saw before going to the payment page? We are a Canadian shop that sells in Canadian dollars. When you change the currency to your own, you are still going to be paying in Canadian dollars. For example, your order totals $20 and then when you go to pay, it says $25. That is because the $20 represents your own currency and when you get to the payment page, it is showing in Canadian dollars, not your own. When you get your credit card statement, you will see that the bank has changed the currency back to your own. PayPal converts it immediately, so you will see exactly what you are paying. We do not add additional fees etc, the difference is simply the currency rate difference.
