Rolex discount in St. Thomas?

[Leibrecht]

I am new to this forum and have enjoyed reading through the posts. I currently own several watches - including Omega, Baume & Mercier, Maurice Lacroix and Cyma - but have decided to take the plunge with Rolex. I will be going through St. Thomas in June of this year. I know that AH Riise is the authorized dealer there. Can someone please let me know what kind of discount I can expect to find there? I would love a Daytona, but don't think I would be lucky enough to find one sitting on the shelf. So, I am looking at either a stainless Submariner or Explorer. In addition, are there any drawbacks to buying from an AD outside of the US?

Thanks for all your assistance and advice.
