Well the irony of people, is we all love free stuff. But we also afraid of it, that is the reason why $1k method still got sold today, even thought the exact copy is available for free. Putting price on something make people think that it ensure some quality.
Easier example, unknown leather bag $100 vs unknown branded bag $10k. Even with exact same quality, most people will think the branded bag is better, and why unknown branded? When you tag thing that expensive than advertise it, people will think this is new brand. As fore chea product most won't event care what brand it is.
