Price discrimination
DanielBMarkham: "sellers either don't know value of their product OR they are always trying to exaggerate it."You have a misunderstanding about value. Sellers CANNOT know the value of their product -- the value of their product is determined by each individual buyer given each individual buyer's circumstances. There is no "universal" value for a product. Products are traded for money all the time at various price points based on millions of criteria.It's this misconception that's causing your problem.
