I guarantee they make more than $500 per game. If there was a master list of every part on the machine and its cost im sure everything adds to a pretty penny. But bottom line is those gi led boards that they value at 60-70 bucks is literally a $5 part to have manufactured and you cant tell me there is not skin on the bone somewhere. If they came out and said (with proof) that the cost of the playfield is $550 (which is prolly right if a CONSUMER gets something at cost however when you order 1000 like a manufacturer the cost should be much less like say $350-400) and they were selling them as low as possible. From there they should paying for the shipping as well as include random JJP swag for the troubles.
*Edit Yes MARCO is awesome. When I put in those $400 random part orders with 200 different things on it. It is inevitable that something is wrong. Missing bulb wrong screw whatever it was they had a replacement on the way within a day (even let me sneak a item I forgot one time). And to top it all off if you catch them at a pin show free shipping and if you chat them up you can haggle the prices a bit (think i got an extra $10 off at TPF on top of the discounts that were already posted) and every little bit counts
