This is true, HOWEVER..... if you haven't checked the price of copper wire (or pipe) recently, you should probably take an AED or your cardiologist with you, cause it has risen to an heart-attack level, partly because of the increases in raw materials & manufacturing costs, but also due to extreme levels of theft....
Around me, anything & everything that is made from, with or containing copper.... pipe, or wire, even 1/4" Icemaker tubing & fittings, is locked up behind industrial-level steel cages with military grade padlocks that require 2 different keys to open, and even then, there is a 9-step protocol you have to agree to follow in order to make a purchase
BEFORE they even open the cages....
I recently went to buy an 8' x 1/2" copper grounding rod, which a few years ago, used to run about $35-45 and were easy to shop for from the open pipe racks next to the plastic conduit, now they are $188 and locked in the above cages, yikes
