Ant more you also need to factor in your state sales tax; so by the time you add CC fees - 3-4%, sales tax - 7-9%, shipping ~15%, and transfer fees ~ $35..............
And.................it's still cheaper online.
Remember, sales tax and credit card fees are a wash being that both your LGS and that internet retailer are charging for both. Shipping one firearm from Bud's to me cost less than what a minimum wage clerk get paid to sell you a gun in a LGS. You ARE paying for that guy across the counters salary/wage/benefits btw. Transfer fees? Well if you are paying $35 you need a new transfer dealer.....thats on the high end. $35 means he doesn't really like doing transfers.
I'm a home based dealer. I sell a few hundred silencers every year, but on Title I guns I only do transfers........more than 2000 per year. And my business hasn't slowed one bit because of South Dakota vs Wayfair. While no sales tax was a great benefit to online retailing until Wayfair, it has had little to no effect in the gun business.
Both have similar expenses such as rent, utilities, employee payroll/benefits, etc..........but look at the differences:
Local gun store- your primary market is a radius of twenty miles maximum vs internet retailer whose marketplace is the entire USA.
Local gun store- depends on walk in traffic during business hours vs internet retailer who is open 24/7/365.
Local gun store- buys firearm inventory from distributors vs internet retailer who is manufacturer direct or gets best discount a distributor offers. Volume means better wholesale price.
Local gun store- needs a clerk to "make the sale" vs internet retailer who only fulfills purchases.
Local gun store- may do as many firearm sales in a year as an internet retailer does on Monday before noon.
Local gun store- is happy to make 5% net profit on a firearm sale vs internet retailer who is even happier selling 10,000 of the same thing with a net profit of 1% per firearm.
Local gun store- selection is limited to "what you see is what we got" vs internet retailer who likely carries 30-60 (or more) manufacturers and dozens of models or calibers in each line.
Local gun store- may buy a few pallets of ammunition per year vs internet retailer who buys multiple truck loads AND has drop ship available from the factory.
