Pueblo Sub Base is the closest and least desirable option. You can walk/dinghy to Moe's in Charlotte Amalie or Yacht Haven. There is a better Pueblo by Yacht Haven.

Even better, rent a car for the data or taxi to Cost U Less, The Market STT, or Price Smart (subscription).

If you're chartering with Waypoints, ask them about a provisioning service... and I look at the user name - Hi Marianne!
