I don’t know about pinball but I’ve done a lot of retail in my life and have experience with more expensive retail atuff like cars. I can tell you they make more than 500 per machine. A prime example would be a $5 led that they charge 40 bucks for? Not going to count but I assume there is at least 20 of them. 35 bucks profit x 20 leds is more than 500 bucks. Keep in mind this accounts for less than 5% of the machine. Workers cost money lights cost money and space costs money. This is why the machine costs 9k instead of 5k. It’s not the cost of parts it’s all the other things. If jjp isn’t making enough profit to cover the cost of replacement play fields they have serious logistical problems. On top of that there is going to be markup at every single stage. So the parts manufacturer makes money. Jjp puts it together to make money. The distributor makes money.
