On Monday, George goes to Harry's fruit store, looking for a bargain. Harry offers to sell to George 100 bushels of grapes that have just been delivered to his store, for the price of $20.00 per bushel. (The regular market price for grapes is $50.00 per bushel.) Harry also tells George that the best time to sell grapes is within a couple of days of delivery. George says: "Let me think about it and I'll get back to you." George rushes out of the store, and spends the next few days looking for a buyer willing to pay market price for the grapes. On Sunday, George finds a buyer. He rushes back to tell Harry that he accepts the offer. Harry replies, "You're much too late, I sold the grapes to Mr. Smith this morning.
