#1 - This machine purchase is for a business, not a home collector like most of us are. As such, it's a huge tax write off for him, including the electricity used to run it. That's a huge savings right there.
#2 - If that machine pulls people in the door, it's creating brand awareness. On top of that, it may just get some people to look around & buy something they otherwise would not have. That equals more money for him.
#3 - The machine will probably generate word of mouth advertising for the owner as well. Many people have never seen a pinball machine, don't know what they are & don't even know they exist. I'm sure many will play it & pass the word along to family & friends whose curiosity will be piqued & they may go down there just to see it & play it. They may even buy something.
#4 - The machine also acts as an advertising tool as I kinda mentioned above.
Companies spend tens of thousands to millions of dollars on advertising every single day. Some is successful & some isn't. This is a nonstop advertisement to anyone walking by that store that will say, "What the heck is that thing!?" & go in & check it out. They may play it & maybe even look around & buy something. You never know.
At the end of the day, paying $40k for that machine is just silly, imo. There's so many others that are far better & far less expensive. But as I said above, there's a cost associated with doing business & that's what this purchase was for this owner. Having that "Supreme" brand name on there is what makes the difference.
That all said, I hope he does well with it & it brings him some solid business & in turn brings us some new people & families into our beloved hobby.
