Yeah, I understand what you mean. Ordinarily, it shouldn't matter what other people are spending on their vintage stuff. It's not my money.

The problem comes when sellers realize that they can get people to pay more money for their retro wares, and I now I want to buy something and suddenly the prices are too high for my budget.

That's what I was talking about with the mouse story. People were selling these mice for peanuts about 3-4 weeks ago. People like me bought them. And now these sellers want to make even more money. So their prices have risen accordingly.
