You're welcome tmsxmsails. You can also get some great info by reading some of the trip reports or posts asking for recommendations. We stay on the French side in Grand Case and the Fr. Cul de Sac ,so if you have any other questions I'd be happy to answer.
I also just remembered that I do know someone who does boat provisions, so I looked up his business name. It is firstmatesolutions.com
This is owned/operated by Sebastian who used to run the watersports at Grand Case Beach Club. He then was Captain on a catamaran, Fun Seaker, until it was destroyed in a hurricane. Hope this helps.
