Shopping for a Speedy

I’m going on a Caribbean cruise over the holidays and I’m looking to get a Speedy. Nothing crazy, just the moonwatch professional, 42mm, black dial, hesalite, steel band. What I am looking for is a deal. I’ll be hitting St Thomas, Antigua, Barbados, Martinique and Dominica. Are there any AD’s on those islands? And does anyone have any experience in negotiating something below retail prices in the Caribbean?
