Jack spots an advertisement in a magazine for kids toys being sold by Kiddies R Us. In the advertisement, toys are advertised for low prices. The advertisement states that prices start from as little as $5. On Monday, Jack emails Kiddies R Us and asks the local store to hold ten (10) of their Big Boss toy trucks for him, for a week. He attaches a receipt confirming the electronic payment of $50 for his purchase. Matty is the manager of the local store and receives the email request from Jack with the attached receipt. Matty checks the prices and finds that they are listed for $9.00 per item elsewhere and have been misprinted in the magazine. She responds to Jack by email explaining this and indicating that he will need to provide an additional payment to secure the purchase of the toys. Jack responds to the email and offers Matty $7.00 per toy stating that he is buying bulk and should receive a discount. Matty responds to Jack by email suggesting that he can have them for $8.00 per item because he is buying so many'. Before Matty responds, Jack arrives at the store to collect the items and a sales assistant at the checkout tells him that he will be charged $9.00 per item (less the payment made), Jack refuses to pay and argues that he has secured a better contract with Kiddies R Us. Required: Identify and discuss whether there is a valid contract here. Have all the required elements or contract been fulfilled? Advise both Jack and Matty (10 marks)
