Friend of mine has a cigar store. Bought the store, not so much to run the business but because cigars are a hobby to him.
Basically, he says that it's a retail business and success is determined by how well you run it as a retail business. Doesn't matter if it's cigars or books or automobile tires. It's more about cultivating customers, having good prices, location, good hours of operation, etc...
There was a "new" cigar store in Baltimore, Adam Leaf & Bean. Openedto a lot of fanfare. Had deep pocketed investors behind it, large inventory of cigars and accessories. Generally had a lot to offer, but I always felt they needed to do double the business to stay open. The fact that the store was physically located about halfway between two other established stores I think worked against them. Anyhow, despite how well stocked they were and all their hard work, they closed in under three years of operations.
My advice would be to go slow & be careful; there's success in the long run.
