I disagree. The purpose of the marketplace is to make sales.
And that is the essence of this conflict/
Some stuff is cheap because there is no demand. Some of such items are niche items with low demand, and some of these items have no merit and will never have demand, and are in oversupply.
So far all of the specific examples are items which are in over supply. Even @left_coast_books Toni Morrison book looks like it is in oversupply, even though it isn’t because it shares an ASIN with books which are in oversupply.
Can you provide an example of an uncommon item with only a few offers which has encountered an problem with too high a price leading to a listing being closed?
