Enough Markup?

[John M. Formsma]

List,

A lady called my mother (my mom is a piano teacher) today asking her about a
local guy who she thought might have charged her too much. Turns out that he
had installed a new Dampp-Chaser rod in her grand. He only charged $800. Do
you think that's enough markup and would sufficiently cover the labor? ;-)
