I have never seen a Riteway or CC boat, so everything goes on the Scrub ferry, or you could pick it up by dinghy in Trellis. Beverages are cheaper at the importing company, so prices of brands vary according to where you buy.

If your friends rent a car from the airport, they could hit all the markets, including the French Deli, butchery, fish store in Pockwood Pond and supermarkets.
