JJP will set its pricing at current levels until the market is no longer willing to pay it. Are they pricing themselves out? Not yet... if they were, they’d be out of business yesterday.
You may not like the pricing, but apparently it fits their needs for sales.
I agree with everyone that expresses frustration over market prices... but the reality is: you gotta pay for certain eras of games. And there is plenty of pinball to be had for less coin - EMs and some late EMs/early solid states - that still deliver the magic of the game.
