What is the duty-free allowance from Caribbean?

[DonPat]

Next month we will be sailing on a 13 day Caribbean cruise. Is there a dollar limit on purchases we can bring back to the states without paying extra fees? Is it a limit per island, or just a total limit? Two of our ports will be St. Thomas and Puerto Rico. Are there different, separate allowances for those islands, considering their special relationship to the U.S.?

Is there a govenment web site that could give me complete information on this? (for instance, I think I've heard that there is no duty on artwork).

you can check out www.travel.state.gov for basic travelers information and www.customs.gov for duty free and customs declaration information

Thank you so much! It's really confusing because the rules seem to be different for different islands. I knew there must be an official web site, but didn't know where to begin. I even tried to "google" it, but probably didn't word it properly.

These message boards can really be helpful! Thanks again.
