I have a
feeling that most of them don't have inventory, but "know
someone" who does, and there's only a few stockpiles that a lot of
resellers list parts from.
Half true - many have inventory piles, but there is a lot of behind
the scenes bargaining with those "someones".
One of the big reasons for RFQ and PUR is to keep cheapskates away.
It'd be interesting to know how much stock actually sells, I suppose (as
opposed to it eventually just being dumped for any scrap value because it's
in the way)
