You're not paying for the repair. You're paying for the peace of mind that comes with a "legitimate business" that you can sue if their shop burns down with your car in it, has an expensive machine that avoids discharging refrigerant, follows labor law, etc. It's the same reason people pay more for products that are ethically sources. That said I think the prices are crazy and would be lower if the financial burden of running a "legit" shop weren't so high.
