I honestly think it's best avoided this time round. Don't like the sound of any of that. Suits me, because I've overspent recently anyway. Not sure if they can or would enforce the "only users in Spain" thing. Also, British buyers might want to think twice because of the scary exchange rates just now.
Just to add, last time I paid through PayPal using a German euro credit card but still had to pay exchange rate fees!! So something's badly wrong with this whole set up.
