Mavis sees the advert on Tuesday. She thinks that the paintings are by the famous artist Dale Salvadori and immediately sends an email to Wilson saying that she will pay £200 for both of them.
Wilson emailed back on Wednesday morning saying that he will accept £200 per painting and that Mavis should communicate her decision to him no later than Friday morning.
On Wednesday evening, Wilson receives an email from Polly. It states that Polly will pay £500 for both paintings.
Wilson responds to Polly’s email straightaway, saying: “It is a deal. They are yours”
On Wednesday evening he also sends an email to Mavis informing her that the paintings are no longer for sale. Mavis’ email account is hacked on Wednesday morning and she cannot send or receive any emails. She sends a letter to Wilson on Thursday morning saying that she is happy to pay £400 for both paintings.
