As far as I know, any bags that you receive from any of the grocery stores on island, you have to pay for. I don't know for sure if plastic bags have been banned or not, but they don't give them out for free. I don't think you can even buy plastic bags, other than reusable ones, at grocery stores. That doesn't count the little flimsy things to put veggies in. We put a few reusable bags in our suitcase, folded flat. They take up no space.
