How Does Harvey Get Master Distributors to Distribute an Unknown Product w/o Advertising?

This question ties in with Bob Blaggs

Question: 5 What is the best way to get distribution for a product?

Harvey recommends getting master distributors to distribute your product via the major chain stores.

However according to Joe McVoy & Ken Hakuta you won’t get your product accepted by any master distributor unless it’s supported by national advertising or PR via the major TV Networks or National Newspapers.
The reason why because it’s not a proven & tested product for generating sales.

In fact, Joseph Cossman used PR to get his product exposed & accepted & likewise for Ken Hakuta to launch his Fads.

So how Does Harvey Get Master Distributors to accept & distribute an Unknown Product w/o any Advertising? & How does he overcome the objection of an unknown product w/o any advertising or PR support?
