Would you not have a much higher profit margin if you were the only shop in town?
Sorry, but I hope you really do have thick skin.
First off, you can learn most of this from your local community college business courses. You will NEVER 'own" the market when you're dealing with service. You may run this guy out of business in 5 years, but what IF, someone else has the same idea as you? Someone that opens up in 3 years? Now what? You have to run him out.
Here's a good scenario that ACTUALLY happened. Town has 7 accessorie shops, all do a fair share, one is larger than the other 6. Big bucks guy buys this shop and decides to do the same thing you are mentioning. Lower prices below cost so that the others with smaller pocketbooks would fail. In 1 year, one of the shops was gone. In 2 years, only 3 were left. In 4 years they were the only shop in the town of 80,000.
They jacked their prices back up to normal retail, and within months of the last shop closing, there was a smaller repair shop that opened a new showroom and suddenly.... there's 2 shops again. In 1 year, there were 5 shops and they were ALL WITHIN 2 miles of each other.
Mr. Big Bucks lost millions because he never could turn a decent profit. So now, they have a bad reputation, HAD to raise their prices, and their competition is fiercer than ever.
Best advice I can give you is to quit worrying about having competition and just run your own business. Heck, make friends with the guys if need be. Just don't take the low road. You'll just make enemies, frustrate yourself, and lose yourself a lot of money.
