Saw this old thread, and it might not be relevent any more for your freind. For the last couple of years, I have done some work in Costa Rica, and have been five times; I think. Regardless, the duty free has a few good deals, at least as of last May: $25 Caol Ila, $55 Highland Park 18. They also have had decent deals on Balvinie Double Wood (1989 and then 1991), but forget how much those were. They have a good selction of the Macallen Fine Oak series, prices only ok.
