Volkswagen ignition cylinders.
When I worked at Vw, we had to constantly order ignition switches because either they are cheaply designed or cheaply made. So when we would place the order from Volkswagen North America, it gets shipped directly from the manufacturer (either Huf or Valeo). And they would include the invoice in the box.
Well, Vw would charge the dealerships $99.95 and set MSRP at 129.95. The invoice from the manufacturer to Vw, showed cost to Vw being $14.95
