How much profit do the scrap yards make per pound?

That sites prices are very deceiving cause their prices are based upon 20 ton (40000lb) at a time.

Nothing is ever exact or clear cut, like I said, its a good indicator to see if you are getting a fear price at the yard.

There are a lot of posts in this thread that are misusing the terms profit and margin.

Margin is the percent difference between what the yard pays per lb and what they sell per lb.

Profit is the percent of the margin they have left after all expenses.

A well run efficient yard can operate on a smaller margin (offer you more) and still make a better profit than an inefficient yard in most cases.
