I was reading this article in M.A.D.

civi0699.htm And was struck by the paragraph wherein the dealer was getting sued for paying beneath market price for things. Isn't the whole business about paying beneath market price and then selling at market price for-pardon the obcenity-a profit. If I make someone an offer and they accept it at which point am I commiting theft? If I get the object for 1/100th market;1/10th market ;1/2 market?
