Board grading

[mrsamsonite]

All boards "were" Not created equal, maybe they are today, but, that didn't used to be so. Imagine going to the store and getting Ribeye steak for the price of low grade hamburger. Or maybe offering them hamburger price if you buy all their ribeyes. Would it work there? Probably not
I've seen it spoken about the "mix", when one seller sends lower grade, and gets the same price as one who sends higher grade, as being an acceptable practice.
I've also seen it stated that although higher grade boards in the same category improve the "mix", they are Not given any further adeu. But why not?
If you buy(or sell) one gallon of lower grade gas, or whether you buy 500 gallons, it will be the same PPG
If you buy(or sell) One pound of Hamburger, Chuck, Shoulder, Strip, Rump, or Roast, the price will remain the same whether you buy a single slice, or the whole store
I, for one, don't understand the difference. IF the boards are a better grade, no matter the volume, why aren't they addressed as such?

I worked 8 years in a meat department.
-We would sell the same piece of meat for less if the customer bought a value pack (3 steaks or more).
-When top sirloin was on sale for $1.99 people would ask for it to be ground into ground beef so they can have Ground Sirloin for cheap. Ground Sirloin is never $1.99
-Restaurant owners from local restaurants would come in and buy several cases of meat at discount prices.
-We would mark down meat that has a couple of day left on their shelf life.
-When there was a surplus of one type of meat we would mark it down to get rid of it.
-When rib roasts were on sale but, not the rib eye steaks, people would ask for the rib roast to be cut into rib eye steaks to get the discount price.
-Sometimes we would put different kinds of steak in the grinder to get a leaner or more fat ground beef. Those different steaks were different prices but in the end we sold them for the same price.

So what I am trying to get at is that like the meat industry the ewaste recycle industry there are lots of variables as well. The price is whatever the company wants it to be and the seller/buyer can make their decision if they want to do business with them or not.
