Clamato can be found in Negril, we got some at the HiLo back in October. This past trip (late December) they didn't have any, too many Cdns in town I guess I did manage to get a caesar at Seastar. Canoe usually has them as well, but didn't have any Clamato when we were there for the mini boardie bash. That was disappointing, I was really looking forward to a caesar by then.

Next time I'm going to bring some with me, I just have to figure out how to pack it
