Went last year - took the fast ferry out of Capt. Oliver's, shopped around town, Hermes is no longer in Marigot and only St Barths - great prices compared to the states (still $$$) but I was looking for something specific. Longchamp had great pricing also compared to the states. We then took a taxi to Nikki Beach - hung out there for the afternoon, ate, drank, listened to music, then taxi that dropped us off came and took us on a 30 minute tour back to the boat. My friends treated for the day so no idea prices - other than not a cheap day but well worth it!!!
