St. Thomas is simpler. For us, we get a taxi or transport to the east side of the island where we meet our excursion host. Moe's is right there so when we return we can hit the store before returning to the dock. There are also 2 stores(1 Eyed Jacks and Al Cohen) very close to the dock (walking distance). None of the 3 stores on St Thomas have web sites so I can't see what they offer or prices. Also, none of the information I wrote in this thread is first hand. I'm hoping other can shed some light on the subject.
