If they did, I'd tell 'em this joke:
A guy spends his entire career working in a plant. He knows the place inside and out--better than anyone else in the place. One day he finally retires, takes his gold watch and goes home.
About a year later, something goes terribly wrong with one of the machines. Not even the machine's manufacturer knows what the problem is. The company is desparate and they beg the retiree to return as a consultant to diagnose the problem.
He walks in, looks around for about five minutes and draws an "X" on one of the parts of the malfunctioning machine. He then informs the plant manager that his fee is $50,000. The plant manager realizes that this is a lot more than they ever paid the guy when he was an employee so he asks for an itemized invoice. This is what he got:
Chalk Mark: $1
Knowing where to put it: $49,999
==========================
If you think that the expertise to design and wind pickups isn't worth a lot, try winding your own. If you place any value on your time, even Custom Shop pickups are a bargain.
FWIW, I'd bet that the raw materials' cost is more like 2-3 bucks (unless magnets are way more expensive than I'm guessing) in industrial-size quantities. Of course, having winding machines, employees, buildings, and all that stuff add to the cost as well.
