What? Did you even read what you typed? These "rules" you mention are irrelevant. They don't even apply. Your response is comparing two entirely different business models. I suggest you spend more time on the tool trucks and think about the products they sell. This is especially true for Matco, unless you like paying a premium for literally rebranded and repackaged Gearwrench, Sunex, Launch and Lisle tools. But to each their own.
I could spend an hour typing up a lengthy response to your post... But I'll save us all some time.
#1. Who owns Snap On? Give you a hint, they are NOT owned by an international mega corporate conglomerate tool manufacture like MAC in the form of SD&B.
This is an important distinction because MAC is essentially a **** shoot of a more than a dozen different companies being rebranded as MAC. Buying a MAC branded DeWalt impact for example is not the same as buying a Snap On branded impact.
Yes, Snap On does own a few other companies (Williams, Bahco, CDI, etc.), but Snap On is their parent company. Not the other way around...

#2. Where are the majority of Snap On tools made? They are made in house by Snap On in the USA in Snap On owned manufacturing facilities... You know, as opposed to Taiwan or China. Like SD&B having their own facilities in Taiwan is somehow a direct comparison. An important distinction beyond just COO itself is the act of outsourcing your production, regardless of whether it's an exclusive product/contract or not.
Disclaimer; These are general statements and don't apply to 100% of Snap On or MAC branded products. I'm referencing hard line tools. Tool boxes, electronics and even specialty tools fall into a different category of their own. We're also not talking about the past or future, or their "economy" brands like BluePoint or SilverEagle, etc.
