Cozumel's main souvenir-shopping area is downtown along Avenida Rafael E. Melgar and on some side streets around the plaza. There are also clusters of shops at Plaza del Sol (east side of the main plaza) and Vista del Mar (Avenida Rafael E. Melgar 45). Malls at the cruise-ship piers aim to please passengers seeking jewelry, perfume, sportswear, and low-end souvenirs at high-end prices.
Most downtown shops accept U.S. dollars; many goods are priced in dollars. To get better prices, pay with cash or traveler's checks—some shops tack a hefty surcharge on credit-card purchases. Shops, restaurants, and streets are always crowded between 10 AM and 2 PM, but get calmer in the evening. Traditionally, stores are open from 9 to 1 (except Sunday) and 5 to 9, but those nearest the pier tend to stay open all day, particularly during high season. Most shops are closed Sunday morning.
When you shop in Cozumel, be sure you don't buy anything made with black coral. Not only is it overpriced—it's also an endangered species, and you may be barred from bringing it to the United States and other countries.
