The best place to buy REAL Cuban Cigars in St Martin is La Casa Del Habano. Go see Carole--she is the owner and will take good care of you. She is located in Marigot. Hours vary based on the season, but she has a great variety of all Cuban brands.

I have also smoked Andi's DAS cigars--very nice smokes as well. As others have indicated, they are available in different places throughout the island. I don't have enough info to tell you exactly where to buy them, but very nice smokes too.

Good luck-enjoy
