When traveling overseas make sure to use a credit card that doesn’t charge foreign transaction fees. Additionally, use one that offers ‘travel rewards’ so you can redeem credits against travel transactions. A good example is the Barclaycard Wold Elite Mastercard which offers no foreign transaction fees and 2.2% back on all purchases towards eligible travel purchases (gas, hotels, & others). Capital One also has a no foreign transaction fee card and offers 2% back on all purchases towards travel related purchases.
Next time you travel overseas, make sure you aren’t carrying on any extra fees!
