PROBLEM SCENARIO: Timothy and Grace went shopping for Christmas presents in Gladesville Mall, in Sydney. Drawn by the window display, Grace went into FinePrice Pharmacy. She chose three gift boxes of bath salts and soaps. A ticket on the shelf read 'One box $12.50, two boxes for $20'. She took her purchases to the cashier, and simply placed them on the counter saying nothing. The cashier scanned the items, and presented the credit card reader. Grace tapped her phone on the machine to pay, picked up her bagged purchases, and left the store. She only discovered when she was looking at her purchases at home that she was charged, in total, $37.50 for the box sets. Grace is annoyed as she thinks she should have been charged $32.50. Does Grace have a binding contract for $37.50, or can she complain? Timothy went into a game store. In the window there was a display of a figurine from a PC game his father used to play. Timothy thought this would make an ideal present. He went to a staff member, Bianca, and asked to buy the figurine in the window. Bianca told him they did not have any remaining stock, but she could take his details and contact him when more stock arrived. Timothy said that it was not convenient to return to the mall, and he wanted to buy the actual figurine in the window. Bianca said she couldn't interfere with the display. Timothy is furious, so says they have a binding contract and Bianca must hand over the figurine in the window otherwise he will sue the store for a breach of contract. Does Timothy have a binding contract with the game store with respect to the figurine? Timothy and Grace enter a coffee shop and order two coffees to take away. One was an expresso and the other a mocha. When Grace handed cash to the server for the drinks, she was told that the previous customer, as a Christmas gift, paid for the expresso. Happy, she paid for the mocha. However, as they walked away Timothy realises, he had not been handed a mocha but rather a hot chocolate, which is the same price as a mocha. He goes back to the server and complains demanding a new drink and a refund to compensate for the inconvenience. Whilst they are prepared to make a mocha, they insist that he pay for it. He is refusing. Did he have a binding contract for the purchase of a mocha
