As a consumer, what does “factory authorized clearance” mean to you? Probably nothing, really. Yet it’s used all the time to indicate “sale”. Why should we as consumers care that the clearance is factory authorized?
I’m guessing that either it use to mean something to consumers in the past or the merchants are legally (by law or contract with the manufacturers) required to say it. A quick google of it turned up nothing but merchant sales, surprise surprise.
These are the things that go through my mind at the gym in the mornings.
