How are sales to end-users conducted?

Hi Mike -
I am a consumer goods supplier -and I have very little scrapping knowledge, but an extensive background in logistics and manufacturing. I contract for finished goods however I get pushback from the factories on materials availability and costing (typical) - so I'm looking for a better way to get raw goods. Hence my interest in buyer-seller connections.

Your response seems defensive - my intent was not to offend, merely to reach out to learn. I will take your suggestion to read past threads to learn more.
Regards,
Will
