I really don't understand why this is such a huge thread...its very simple. There are only a few cards that charge no fees for foreign transactions.
Capital One is the most common....what else do you need to know? Instead of trying to figure out forex spreads, atm fees, transaction fees, exchange rates and other everchanging numbers...just put a Capital One card in your pocket, call them to make them aware of your travel plans, and buy what you want for the price listed....simple
