Andorra has the euro € as its sole currency along with 24 other countries that use this common European money. These 24 countries are: Austria, Belgium, Cyprus, Estonia, Finland, France, Germany, Greece, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, the Netherlands, Portugal, Slovakia, Slovenia and Spain official euro members which are all European Union member states as well as Andorra, Kosovo, Monaco, Montenegro, San Marino and the Vatican which use it without having a say in eurozone affairs and without being European Union members. Together, these countries have a population of more than 330 million.
One euro is divided into 100 cents. While each official euro member as well as Monaco, San Marino and Vatican issues its own coins with a unique obverse, the reverse, as well as all bank notes, look the same throughout the eurozone. Every coin is legal tender in any of the eurozone countries.
Andorra La Vella is a good destination to buy all kinds of cheap goods, due to the country's status as a "tax haven."
However, do compare the base price with that in your own country or region. Tax free does not necessarily bring you net lower final expense. If you don't just want to buy new releases of brand-name luxury goods, whose base prices can be very different from the "just arrived" category, Andorra is not the right place for you. Just wander around then, it is also very enjoyable.
