You would think that would be simple but not in this hobby. I have no idea why people can't just move along when the price is out of their range.

The seller gets to price his own property based on what it's worth to him. If no one wants to pay that price then he gets to keep his stuff. So fucking simple but people lose their minds over prices they don't like and then treat the seller like shit which is a much worse behavior than asking a high price for an item you own.
