We never charge for anything other than the amount listed during checkout and in your order confirmation. You'll also be able to confirm this in the receipt you receive after payment is complete.
If you're seeing additional fees (e.g. foreign transaction fee) charges on your card, it’s usually because some banks will still charge you a small Foreign Transaction Fee or International Processing Fee for making purchases from businesses in other countries. Even though we try to keep things simple and efficient by charging you in USD, this is something we have no control over — it's solely up to the discretion of your bank and having to do with your account and card type.
