Because Leo is going to London tomorrow, Johnny says that trick is that stores will charge you a transaction fee if you want to pay in dollars. Just let the credit card charge in local currency and you'll save money. Unless your card has a foreign currency transaction fee. So check the fiine print. How about getting cash? Johnny Jet says to go to the ATM machine. Don't go to the exchange, and don't go to the hotel, they really get you. Also T-Mobile offers unlimited 2G data for free. That's cool. Also don't pay with a credit card when using a taxi, they charge you a fee as well.
