Cuba is not generally considered a shopping destination. Mostly, you’ll encounter state-run shops or hotel shops, where prices are fixed. Such locations sell very basic necessities, along with items like beer, coffee, or rum. On occasion, you will find open-air or craft markets in Cuba. To find out the schedule and location of the markets, ask your Cuban guide or hotel concierge.
Opinions vary on whether negotiating prices for artwork is acceptable, but keep in mind that Cubans earn a fraction of what most travelers to their country do.
As of October 2016, the monetary value limitations on what authorized travelers may bring back to the United States as accompanied baggage has been removed. In other words, authorized American travelers may now bring back as much rum, cigars, artwork, etc. for personal use as they can fit in their luggage. Please see U.S. regulations on import good for non-personal use items.
