I would also be surprised if a company ships rejects to someone evaluating
their products. Risk a sale, tarnish your reputation for a part that costs you
ten or twenty cents to make? Also you would have to have separate
stockroom space to hold rejects. It is more trouble than the cost savings.
I can see the end of the quarter push when you run out of the "good stuff"
and someone ships the "samples"
I worked at Analog Devices and Harris Semiconductor (now Intersil) and never
heard of this practice. I think the more likely scenario would be to dump the
rejects in a bin and sell them to a surplus house.
