an excellent example of what I said in this post:

"IF you find something readily available to the public - cleaning chemicals, some kind of machine or tool, etc., - then it PROVES people buy those items to get the results the items provide.

A percentage of people would rather pay someone else to use those chemicals, machines, tools, etc., to do what they could do themselves."
