If you are not particular about your cheese and are willing to purchase a sample pack, the grocery store just through Sandy Ground closer to Marigot (maybe US Market that became Simply)
sells a sample pack of 4-5 cheeses for a extremely low cost as compared to buying them individually. Usually has a goat, brie, a hard cheese, and a strong smelling cheese whose flavor is not as strong as it's smell. Supermarket has great meats counter and "safe" convenient parking. Worth the trip since we get our gas at the Cadisco nearby.
Best prices and 1-1.
