Once you get out of the Virgins you'll start finding local open-air markets with numerous vendors selling fresh produce. Depending on which island you're on, it could be local, imported, or some of each. Prices will vary, too, but produce isn't priced out of line with what you're probably used to. The local produce here on
Nevis costs about twice as much as produce
sold by the vendors from
Dominica, who come here once a week on a rusty
boat. Twice as much as
Dominica is still pretty reasonable. For example, a nice local avocado is $1.85 US vs. $1.11 US from the Dominican boat. A nice, juicy grapefruit goes for $0.75 US vs. $0.38 US from the boat.
The French islands supply themselves. Dominica and St. Vincent export to many of the others, where local produce generally supplements the imports. Produce in the Grenadines is almost exclusively from St. Vincent. You'll also so see stuff from far away, too, like romaine lettuce from
California, pineapples from
Costa Rica, and apples from
Washington state. Buy the local stuff when available. The produce from Dominica and St. Vincent is organically produced and is great.
You can also find local
fish markets on many of the islands. They're not always open, and sometimes just the fishermen with coolers on the sidewalk. When you hear a long,
single blast from a conch shell, it means the fishermen are back ashore and selling their catch. You'll catch on sooner or later that the
price can be negotiable. Sometimes the
price quoted to you will be a bit more than that offered to the locals, but still not all that expensive. We buy snapper and cleaned conch for $3/lb.
