Only had 5 minutes to play and happened to hit the bonus once where the old man sells an item. You are given 3 prices to choose as an offer for an item. After picking on offer to the customer, the customer will then show what price they want to pay. The price the customer offers is your bonus and doesn't match any of the 3 original offers given by the old man. I thought maybe you get extra if you match the customer's offer but as mentioned above they are all different. What is the significance of having to choose the 3 offers? Why wouldn't you always choose the highest offer?
