Earlier quoted context omitted.
If they buy something becsuse it's a penny cheaper, who's really being tricked?
The consumer. $0.01 doesn't make it affordable, it's just a mind trick. You seem to be aware of this, yet you're defending it.
2. Even if you point it out... What changes. Has anyone ever seriously reconsidered buying a product when you tell them it's $500 instead of $499? What's the harm being done here?

I can't tell you how to live your life. But those are the reasons I don't really care.
