As of today, neither one of those Carrefours is open, but the one in Cupecoy and the new one by the med school are open. Those are both much smaller than the other two. The one close to the causeway has never reopened since the hurricane. The one by Mark's had a fire around the end of June and is supposed to be closed for about two months. Otherwise, in Simpson Bay, you have Market Garden. Where the Fresh Market used to be has reopened, can't remember the name of it now, but they have quite a few US products, if that's what you're looking for. There is also one close to the cruise ship pier, again, don't remember the name of it. On the French side, Super U is great!
