When I visited the Bahamas, I saw kids in the marketplace putting Cohiba bands on naked sticks and arranging them in boxes...I'm sure these were snapped up by tourists just as fast as the kids could get them out to the taxi drivers.
I bought some Monte #4 in a John Bull shop...beautiful, locked humidor with an attendant and the shop was full of high end jewelry, watches, purses, etc. that were not fake. Smokes looked fine, but smoked "just okay." I was disappointed, but realize now that it was probably a fake, even though it came from a reputable shop. The shop itself probably thought they were real, but unless it's a LCDH, I would be suspect of any shops buyers.
