* Save on foreign currency exchange: Withdrawing money abroad can cost a lot in charges. Although using a debit card can be cheaper than a credit card, be aware that most banks will charge for each cash withdrawal on top of a commission fee. Best practice is to take out larger sums so you're charged less frequently, only take care and don't keep all your money in the same place. Getting your currency before you arrive at the airport is also a way of securing the best rate you can and works out a lot cheaper.
