The centros comerciales (malls) in Cancún are fully air-conditioned and as well kept as similar establishments in the United States or Canada. Like their northerly counterparts, they also sell just about everything: designer clothing, beachwear (including raunchy T-shirts aimed at the spring-break crowd), sportswear, jewelry, music, video games, household items, shoes, and books. Some even have the same terrible mall food that’s standard north of the border. Prices are fixed in shops. They're also generally—but not always—higher than in the markets, where bargaining is a given. Perfumes in Cancún are considerably less expensive than at home and even than at the duty-free shops at the airport. Of course tequila is a bargain here as well, but make sure you buy at the supermarket rather than at a souvenir shop.
There are many duty-free stores selling designer goods at reduced prices, sometimes as much as 30% or 40% below retail. You can find handwoven textiles, leather goods, and handcrafted silver jewelry, although prices are higher than in other cities and the selection is limited.
Shopping hours are generally weekdays 10–1 and 4–7, although more stores are staying open throughout the day rather than closing for siesta. Many shops keep Saturday-morning hours, and some are now open on Sunday until 1. Centros comerciales tend to be open daily at 9 or 10 am to 8 or 9 pm.
