Thank you for contacting us. No, we’re not that expensive ;-) We use the European Central Bank currency rates via an XML web service service, and it appears that for some reason the values were either sent by them, or interpreted by us, incorrectly. We cache these values for 24 hours, and it they were updated just before you checked and saw the surprising result.
This has actually been in operation for many years without a single problem, so it was a bit of a surprise that it suddenly just stopped working as intended!
Once again – thank you for notifying us of this.
