John is going to buy a car. He wants a used Honda. The salesmen shows him one from 2012. John's not really positive how much the car is worth to him. The sticker says 14,000 and they end up agreeing on 12,000. If the sticker had said 13,000, John might not have agreed to 12,000 - he might have become convinced that the car was only worth 11,000 to him.
