"In both Romania and Moldova the only legal tender is the leu (plural:
lei), though they are separate currencies in each country and have
different exchange rates. In Romania you'll see many prices quoted in
euros, while in Moldova people talk in US dollars. Consequently, this
book quotes prices in euros for Romania, and in dollars for Moldova."
