Anyone using these?
I've just signed up for a Revolut card to see how they pan out for me. You can get it for free if you go through a link from MSE ([Only registered and activated users can see links. ]) and not pay the £4.99 delivery for the card. I get the feeling that it would be hard to really tell how better off you are over a long period from using whatever method you currently use.
That said I figured I'd try it and see how it compares on each individual transaction. Mostly this will be used when I go to see my folks in Spain, so be interesting if its better than using my santander credit card, or converting Euros at the post office the week before I go.
Monzo is another card I looked at.
