I currently use my Nationwide card to withdraw money overseas on holiday as they do not charge a fee for taking the money out but from November they will.
Halifax have now lauched their Clarity Card and you can use it abroad without incurring fees for cash withdrawal/purchasing as long as balance is cleared each month.
Here is the direct link http://www.halifax.co.uk/creditcards/clarity.asp
I just wanted to give people the heads up on this.
Be gentle with me as this is my first post!
