The whole Caribbean basin is served by a distributor called Caribbean Cigar, NV. They sell over 2,000,000 sticks a year. To say that all C.C.'s are fake is beyond ridiculous. Buy from the local LCDH, reputable merchants or at the various resort-owned shops, you will not get taken. If you are buying from some hole in the wall there is a good chance that you are going to be disappointed. Rule of thumb in the Caribbean: if they have a walk-in humidor, you will be pretty safe.
And yes, cigars are expensive in the Caribbean, mainly because the various island govt's. tax ALL cigars at between 100-200% of retail value.
