Poly packs was a joke, and rip-off. They advertised "too many to

pack of 100 you might find 5 functioning transistors, and those
probably had high leakage.
I remember when Digi-Key and Poly Paks both advertised in the back of
Electronics Illustrated, selling apparently the same sorts of stuff.
I don't think so. Poly Paks was around from the early sixties, I think
from reading ads it had a different name to begin with, and were selling
surplus, even in the seventies they'd have stereo amplifiers boards and
calculator boards that obviously had been surplus from manufacturers.
See pp. 97 & 99 of the PDF.
Digi-key started by selling a digital keyer for morse code, and then
added some parts that they sold, eventually getting bigger and bigger.
They always seemed to be selling new parts, first a limited selection to
hobbyists, then as that did well broadening the line, yet still seeming
to be fore hobbyists, and then somewhere along the way they got big.
