I don't want to be a kill joy, but..... There are some older strings where this very topic has been discussed.
Needless to say; the start up costs are very substantial, as they are for any start up business. For a small decent inventory of pipes alone you are probably looking at between 30 and 50 thousand dollars. If you think about it a small selection of only 100 pipes sale prices averaged at $100 each... that's $10,000. A decent selection would be closer to 500 pipes, and if like
The Briary you have around a thousand.... well... the average sale price will climb to $150+ each, owing to economy of scale; multiplied by 0.7, will render approx. actual cost.
$150,000 x 0.7 = $105.000.00 just for pipes and this is just a 30% margin (which is very low).
Some things to bear in mind are; the lower the cost for merchandise to be stocked in limited quantity, the higher the margin, conversely the higher the cost for merchandise to be stocked in limited quantities, the lower the margin. This is where many retailers make mistakes, and push the lower quality merchandise to increase turns on the higher margin product, thus the perception is that the store is oriented toward "the cheap stuff", and your long term viability is compromised. However; if you want
quality the costs for product and operations are higher and a more difficult balancing act to maintain, but
long term viability is increased through quality of product,reputation, and dedication to service (good will equity), thus a higher short term risk. (You must survive long enough to build
good will equity.)
The Briary has been in business for over 30 years, and has Grade A
good will equity and a solid core customer base. That's just for pipes. Your higher margin items would include the product lines listed below.
Then you have accessories, and humidor, and tobacco, inventory insurance, display cases and other furniture, salaries and, healthcare costs, utilities, initial advertising, and subscription type advertising, web site setup costs, and a few other incidentals; e.g. permits. Also, you must choose the correct location. And, as a start up you
will not get the best pricing on your merchandise.
It's a tough business... and I didn't mention "rent", and hopefully customers.
