I was really into cigars in my younger years and it was extremely difficult to get Cubans. Many were fake. Whenever I traveled I would only buy them from the Casa Habana, the official cigar store of the Cuban government.
Politics aside, I think that the Cuban cigars are overrated. I find Dominican cigars to be far more consistent. In fact, I often would fool friends who asked for a Cuban cigar (I had been down there twice for humanitarian aid so I had four boxes of them). I would sometimes switch the label and give them a Dominican cigar and everyone would marvel at how good it was.
Now after that long rambling post, my only point was that I doubt it was that easy to routinely get dozens of boxes of Cuban cigars in the U.S. like they did in Short Fuse. Unless of course back in the 70's things were different.
