I'm a retailer and half the time I can buy cigars cheaper on c-bid, not that I would.
First off all cigar margins are miniscule to standard mark ups. In most states you'll make a 50% margin at best. If you go on Famous or Cigars International they have such huge buying power with no state taxes that I can practically buy cigars from them cheaper then I get wholesale from manufacturers.
B&Ms are a thing of the past I think for the most part. There is very little margin and you have to diversify the business just to make a profit. Its a sad reality but you don't get in this business to make money it's purely a love for the leaf.
