Suppose you were browsing used furniture stores, looking for a well-made desk. The least costly desk you find has a marked price of $70.
"I don't want to pay more than $40 or $50.," you tell the shop's manager.
"Why are you asking $70?" The shop's manager replies, "It's a test of the market." What does he mean?
Why does he not let you have the desk for $40? Under what circumstances might he change his mind?
