Peter owns a small store where he sells vinyl records. He decided to promote the business by advertising a "special offer" in the local newspaper. The advertisement he placed in the local newspaper states that on the production by the customer of the advertisement, the customer will be entitled to purchase "rare" vinyl records by famous Opera singers for only $9 each for one week only. This price was incorrect due to a mistake Peter's assistant made in the email he sent to the relevant newspaper. The special price that Peter wished to advertise was instead $99. The day after the advertisement is published, forty customers arrive at Peter's shop producing the advertisement and offering to pay $9 for each of the records in question. Is peter required to sell these records to the forty customers, for $9 each according to the law of contract? Please refer to any relevant legal cases and/or legislation to support your arguments. Do not discuss the Australian consumer law for the purposed of answering this question.
