Buying Credits in the US

So I was wondering, since that I live in the US and if I buy credits with my US credit card, will there be some sort of foreign transaction fee, since I would be buying the credits in Euros, not dollars?

My advice: use Paysafe cards. Fast, cheap, easy and without any extra costs

Yes, there is a fee.  It is not that big of one, when I last purchased 500 credits I think the fee was just over $1.  But I suppose how much the fee is depends on your credit card company.

It all depends on your bank’s conversion fees. If you live in a small country with its own currency and travel lots I recommend getting a card which charges small or no conversion and widrawal fees. I strongly recomend that the everyday card is from such a bank because over the years you can save lots even in your own country by not paying widrawal fees (although cash is rarelly necessary nowdays).
