At what fees, though? Within SEPA it's now zero. I can buy computer parts in Germany without considering that downside. Kind of the useful for this 'one market' thing they are trying to have going on. And the mental math every time. I can trust that a coffee is going to be a bit overpriced at worst (but not a real mistake), but is it worth driving 5 minutes to a petrol station that sell it at 493 ISK the litre instead of 529 ISK? Should I buy this shirt for 1500 ISK as souvenir or is that insensible? Hard to tell.
