So, if you've been charged a little extra, it basically means that your currency is not supported by our website and you had to choose to pay with EUR, USD, GBP, CHF, or AUD. These currencies might be more expensive than your own currency, thus you were charged a little extra amount.
Let me give you an example to make it clearer, in case you haven’t understood:
If you’re living, for example, in Denmark where they use danish krone (DKK) and you decide to pay with euro (EUR) at Gocase, it means that the amount you paid in EUR needs to be converted to DKK to be accepted by your bank. Now, EUR is a little bit more expensive than DKK, meaning that for DKK to reach the same amount that you paid with EUR, an extra amount needs to be charged. This amount shouldn’t be too big, though, so if you have paid something like double the amount of your order, then it means something is going on with the processing of the payment.
