the funnie this is that the $$$ diference is not seen at the costumers end.

do you realy care the the diode is 3 Cents more (making a 100$ project)from
the low votalge one.......(some stores some cases)

You might be surprised.

In fact, cost reduction is a *big* issue in the manufacture of many
(most?) consumer electronic products.

Look at it this way: if you save three cents on a single part, of
which only one is used in a $100 device... and you manufacture a
million of these devices per year... then you've saved $30,000 per
year. That's not chump-change.

If you can save $.03 per part, and you use ten of these parts per
device, and you manufacture a million units per year - then you've
just saved $300,000, which will cover the cost (salary and overhead)
of at least one good engineer.

Yes, my friend, big electronics companies _do_ care - a lot - about
shaving the pennies out of the bill-of-materials cost of the devices
they manufacture.
