Brenda has decided to sell her apartment. She advertised it in the Straits Times, a local Singapore paper, at S$1.1 million and provided her mobile number. Jonathan saw the advertisement and rang Brenda to make an appointment to see the apartment. Jonathan liked the apartment but could not agree on the price with Brenda. He offered S$850,000.00 as his highest offer but Brenda insisted on S$1.1 million.

On the following Monday Jonathan received an email from Brenda offering him the apartment now for S$900,000.00 and saying that Jonathan can have until noon on Thursday to think about it. On Wednesday evening Jonathan meets his brother James and finds out that Brenda's sister, Rachel, purchased the apartment earlier that day for S$850,000.00.

Brenda goes straight home and writes a letter to Jonathan, accepting his offer to sell at S$900,000.00. He posts the letter immediately and Jonathan receives it on Thursday morning, but replies by return saying "You are too late. I have sold the house to my sister."

Advise Brenda and discuss the issues prevalent in this case.
