Am I going crazy or?

I've been thinking about this for awhile now- I see many things for sale on agon. Some are reasonably priced, some priced to cheap ( those go quickly ) and some things priced for more than anyone will ever pay. I guess the folks that get me are those that over price, and refuse offers. I watch their adds go out after the 33 days. And then some list the add again at the same price. I find this interesting. I know I would not expect them to sell to a low baller. However I wonder why they can't take a hint. The worth of something for sale is determined not, by what the seller feels it is worth, but rather by what the market is willing to pay. And for sure we are now in a buyers market virtually on anything.
