Money
Prices quoted are in U.S. dollars, which is the official currency in the islands.
Major credit cards and traveler's checks are accepted at many establishments. Bring small-denomination bills to the less populated islands—but bring enough cash to hold you over; many of the smaller islands deal in cash only and have no ATMs. Some islands don't even have banks, so get some cash while on Provo if heading elsewhere.
Prices are given for adults. Reduced rates are almost always available for children, students, and senior citizens.
ATMs and Banks
On Provo there are ATMs at all bank branches (Scotiabank and First Caribbean), at the airport, at Graceway IGA Supermarket, Ports of Call shopping center, and at Graceway Gourmet IGA. There are also Scotiabank and First Caribbean branches on Grand Turk.
Credit Cards
It's a good idea to inform your credit-card company before you travel. If you plan to use your credit card for cash advances, you'll need to apply for a PIN at least two weeks before your trip. Although it's usually cheaper (and safer) to use a credit card abroad for large purchases (so you can cancel payments or be reimbursed if there's a problem), note that some credit-card companies and the banks that issue them add substantial percentages to all foreign transactions, whether they're in a foreign currency or not.
Note that some shops require a $25 minimum to charge. A few shops may pass along their 3% to 5% surcharge if you pay by credit card; the clerk will tell you before you pay.
