Tacha, yes you can purchase gifts for multiple bottles of wine, but these are designed for giving as gifts to friends or family that are going on a cruise (you are buying them the wine) But if you are going on the cruise yourself, you would not be saving any money doing this. You are better off buying the wine a bottle at a time.
