Re: Nothing new
There's an "economy of scale" going on here which drives up the cost. Which is cheaper, for the OEM to buy 10,000 of the same part and ship them to one factory in one truck, or for 10,000 people to buy one each and have them shipped individually to their houses?
To be fair, a 10x markup for building something from spares isn't right. But 2x may well be due to the cost of buying one part at a time.
