I wonder if so many people struggle with basic economics because of how hard it is to price things as a seller? I've seen people go anywhere from 'Well, I have a standard x% markup' to 'that should be worth (outrageous number)!' In reality, as the article shows, there are many, many factors to determining a price for something you are selling. I've also had people try to buy things from me as a person (as opposed to a business) and tell me I'm asking an unreasonable amount for it. ... Yeah, because it's worth just slightly less than that to me. That's the point where I tip and decide I'd rather have the money than the thing.
