This is our first time to travel abroad. We have had several requests from friends to bron back different items. I've read conflicting answers about this on trip advisor, yahoo, and cha-cha. According to both TSA and US customs, residents can bring back up to 5 liters of alcohol but only 4 can be carribean basin made, to be included in the $1600 of exempt dutiable items. What exactly does this mean?? What are duty free items and how will I be able to tell the difference?
