Sharon saw an advertisement in a newspaper which referred to a 'special offer while stocks last' by 'Mari-Mari' a local supermarket of a reputable brand of laptops. The offer price was stated to be RM700 per unit. The usual price of such laptops was around RM950 per unit. Sharon rushed to the supermarket, chose one of the laptops and took it to the payment counter. The salesperson at the counter told her that the supermarket had increased the price of the laptop and the new price of the laptop was RM750. Sharon refused to buy the laptop at that price. She seeks your advice whether the supermarket is contractually bound to sell the laptop to her at the advertised price of RM700. Assess the legal position of Sharon.
