As tourists you can bring anything you would normaly carry for a vacation. Cameras, prescription drugs, snorkle gear ect. You are allowed 1 liter of hard liquor, or a six pack of beer duty free I believe. Any more than that and duty kicks in. I'm not sure but I think you can bring two cartons of US cigarettes, but it could be just one. They aren't going to search a regular tourist anyway if you claim nothing and just go through and have nothing to hide. If you bring gifts, or supplies to residents that's a different story. You must claim what you have and have receipts for it to verify it's value. Duty is low on computer gear, just " Stamp " tax. 7%+8%sales tax. Manufactured goods can be pricy, 30% or more. It is not an exact science down there. Sometimes you do well, other times you get hosed. Food stuffs are duty free as long as they are packaged, and sealed. Spices are ok too as long as they are sealed and unopened. I've seen people bring in US beef. I don't know how they do it. I hear you should be prepared to have a few choice steaks on top to give the officer to " check them out ". Maybe someone else knows the laws better than I and can help you more. Hope this helps a bit.
