Each store keeps its own prices and observations. We prefer the latest recorded EUR price for Europa. When the displayed currency differs from the store amount, a separate approximate value may use the latest available ECB reference rate.

Some store links may be affiliate links. We may earn a commission from qualifying purchases, at no extra cost to you. This does not affect prices, ratings or rankings. How commercial links work.
