I want to rant about credit cards charging exorbitant fees on foreign currency transactions.
For example, for our overseas trips we often booked car hire and hotels using credit cards (Amex and Mastercard). I have discovered that the exchange rates they gave were sometimes worse than the CBA retail rates, and on top of these they charged 2.5% fee on the conversion. We complained when we bought foreign currencies from the CBA and had to pay 1% commission. But, having to pay 2.5% conversion fees is a big rip-off.
I would like to hear your suggestions on what would be cost effective ways of paying for foreign currencies using credit cards?
