Patrick visits Josefa's farm after seeing the advertisement. He states that he is willing to buy all 50 bags and pay the price advertised i.e $5000. Josefa says, "The price is now $7,500." Patrick replies, "I will pay $6,500 and that is all." Josefa states, "I am not sure." Patrick responds, "Look, I will give you until next Friday to decide whether you are willing to sell me the cocoa seeds for $6,500." Patrick leaves his phone contact with Josefa. On Saturday morning, Josefa decides to write to Patrick and agrees to sell him the cocoa seeds for $6,500. Sunday morning, Patrick changes his mind and telephones Josefa to inform him that he no longer wishes to purchase his cocoa seeds as Popo (another cocoa farmer in Pacifica), is selling 50 bags of cocoa seeds for a much lesser amount. He leaves a voicemail on Josefa's answerphone.
