Money

Prices for many items on Guam are generally similar to what you would expect to pay at home. Locally produced goods, foods, and drinks are reasonably priced. But like many remote islands, a lot of goods have to be imported and their prices usually reflect this. ATMs are common in all the urban areas and most places accept credit cards.
