People who have stayed here will know how much I bang on about using a Nationwide cash card to withdraw money while abroad. No charges and a great exchange rate, it’s highly rated by Martin Lewis Moneysavingexpert as well.
Now beware.
When you use it, or any card, in Spain you will receive a confusing message telling you that you can see the cost of your withdrawl in GBP if you press yes, this will almost certainly cost you more money due to an inferior exchange rate.
If you want the best rate, remember, just say NO.
