5:30 is particularly early, especially when it involves normal people's hobbies.

This is what the OP was saying, that this space has been been invaded by scalpers, people who do tend to have higher "quality standards" because it's in the nature of their "job", they've become aware that the higher quality stuff sells for more so that they're actively chasing it.

You're either delusional or just being a contrarian if you think being out the door at 05:30 is "not particularly early". McDonalds is still serving the dinner menu at that point.

And you used to be able to find diamonds in the rough on flea markets, secondhand stores and even on online places like eBay, until 2013ish. That's when the professional reseller became more and more pervasive.

Since you seem to think that flipping and scalping is a valuable addition to society, we have nothing to discuss.
