Mango shoes are also sold all around the world in most high fashion districts so you should be able to find them very easily. If you don't live near a large city, however, you may have to stick to ordering your shoes online.
Different websites will have different deals on Mango shoes and depending on where you live you may be subject to additional taxes so make sure to shop around and make sure the site is using your country's currency. You don't want to think you are getting a great deal only to have the exchange rate deal you a hefty blow.
