cdu's quoted copper price, page-31

zzedzz you said,

"Linked to are words that you would use if the price was at a discount."

More likely that the price linkage could be a rolling average over a period.

This avoids the problem of two folk who want to conduct a sensible business fighting every time when the shipment shipped, and the actual price of copper when ownership passed hands etc.

And then zzedzz you said..."Simple really."

Yes correct, its simple really.

Not such a smarty-pants as you think you are.
