The client isnt stupid...
Example they are paying:
Client $37 dirt & $142 rock or $52 composite
Company (1) $28 dirt & $118 rock or $45 composite
Prime $16 dirt & $74 rock or $22 composite
Sub $12 dirt & $50 rock or $16 composite
Sub of sub $7 dirt & $28 rock or $10 composite
Sub of sub workers are getting $4 and have to provide everything.
I skewed prices some what
Now, if the client removes a prime, they know what the savings are, the bean counters love it
