More advice than you asked for
I second the statement about CAO - a must have!
The same can be said for Fuente. The 8-5-8 in particular is a very well balanced cigar that can be enjoyed by newcomer and seasoned smoker alike!
Put together a product matrix of sizes and wrapper types to get a sense of the variety you might stock. Focus on the more popular tastes (medium to full bodied), and carry a little bit of the fringe stuff (candela, flavor infused).
For each "class" of cigar (a size/wrapper pair) think of the cigars that you would enjoy, or ask us for input, considering different price ranges. Pick a couple or a few for each class, depending on the general popularity of that class.
Also, if it's possible to include a smoke room in your establishment, it would definitely be a draw (no pun intended) to get people into your shop. Make the purchase of a cigar a requirement for each visit to the smoke room. It will serve you well in bad weather.
(I have a baby in the house, so I don't smoke at home. I generally take a walk. But if it's windy or rainy (and it's often both in Seattle), I can end up putting off a smoke for days or even weeks. If there were an establishment nearby like a local cigar club, I would go there.)
Just my buck-o-five. I hope it helps; and break a leg!
