(i) McMaster operated a second hand store and purchased an antique chair at a garage sale for $125.00. One week later Lily saw the chair in his store with a price tag of $500.00. She offered $300.00 but requested that McMaster keep the chair for 2 weeks since she was repainting her living room. McMaster told Lily that the chair was worth much more than $500.00 but he would sell it to her since she seemed to be a nice person. He proceeded to prepare an invoice which they both signed. Lily paid a deposit of $100.00 and agreed to pay the balance when she picked up the chair. Lily didn't pay particular attention to the invoice since she didn't believe that the terms of the deal were particularly complicated. McMaster gave her a copy of the invoice and put a \"sold\" sign on the chair. The following week, Andrew, an antique dealer visited McMaster's store, carefully examined the chair and offered $10,000.00 for it. The chair, Andrew explained, was a rare specimen dating to 1812. McMaster accepted Andrew's offer. McMaster contacted Lily and told her that his mother had fallen in love with the chair and he wished to terminate their agreement. He offered to pay Lily $200.00 for her trouble. Lily told him she would like a day to think about it. She was suspicious that McMaster would offer her $200.00 when the chair was only worth $300.00. Lily reviewed her invoice and discovered that the price in the invoice was $500.00. After receiving several increasingly demanding calls from McMaster and feeling intensely pressured and not sure what to do, Lily confirmed that she would accept his offer of $200.00 to release him from their sale agreement
