Bermuda's currency is the Bermudian dollar BMD or B$, which is divided into 100 cents. It comes in all the same denominations as US currency, except for a more widely used dollar coin and a two dollar bill. The currency is directly tied to US currency, so USD $1 always equals BMD $1, and US dollars are accepted everywhere in Bermuda at par. Bermudian dollars are not, however, accepted in the United States.
shopping
A nice assortment of stores exists in Hamilton, especially on Front Street. The area can be explored easily by foot. Front Street, is one of the main shopping streets, and is facing the harbor. In recent years, two of the largest and oldest department stores on Front Street have closed. However, A.S. Coopers, first established in 1897, remains.
Shopping can also be found in the easily walked town of St George as well as in Dockyard, which has a small shopping mall. Smaller stores can be found throughout the island offering a variety of goods.
costs
Bermuda can be expensive. Because of Bermuda's steep import tax, all goods sold in stores that come from off the island carry a significant markup. When buying groceries or other non-souvenir items of that nature, be aware that the best prices are usually away from the more "touristy" areas. For example, one cup of yogurt might cost about $1.60 at a grocery store near hotels; it will cost 25% less at a grocery store further from the tourist attractions, and only 10 cents more than in the United States. When buying these sort of things, go to where the locals go.
