If I am travelling abroad, what it likely to give me a better exchange rate?
- Exchange Bureau
- Pull large sums of cash from an ATM
Note; I've been told that using ATMs is actually cheaper if you do it properly
It depends a lot of the country you are going to.
It also depends on your credit/debit card details. Some cards include fee-free withdrawal, and some cost an arm and a leg if used at a different bank.
So, a general answer is not possible.
