What if Stern sold LEs for 13,500? That's essentially what's happening. Then people would complain that the prices are so high, but in that case we'd be powerless to stop it.
I don't like to see games purchased for the sole reason to get flipped, but the market is what the market is. Some people are just playing the market game. I don't like it, but I also don't think it's ruining pinball. What I definitely hate is when those people get priority in before others who really want the game.
If as a distributor, some of my top buyers were those whose only purchased for the sole purpose of flipping, I would remove them from my list. That would curtail the flipping and would allow more people who actually want the game to be able to buy the game.
