(a)Aminah saw an advertisement in a newspaper, which referred to a ‘special offer while stocks last’ by a local supermarket of a well-known brand of vacuum cleaners. The offer price was stated to be RM100 per unit. The usual price of such vacuum cleaners was around RM300 per unit.Aminah rushed to the supermarket, chose one of the vacuum cleaners and took it to the payment counter. The salesperson at the counter told her that the supermarket had increased the price of the vacuum cleaner and that the new price was RM320.Aminah refused to buy the vacuum cleaner at that price. She seeks your advice whether the supermarket is contractually bound to sell the vacuum cleaner to her at the advertised price of RM100.Required:AdviseAminah. (5 marks)
