(a) That's right. A supplier might display (advertise) goods or services at more than one price. If more than one price is displayed for the same goods, a supplier should supply the goods at the lowest price. Section 47 of the ACL prohibits the supply of goods, in trade or commerce, at the higher price. Pecuniary penalties can be imposed on the supplier for such conduct. Such conduct is made also made a criminal offence by s 165, punishable by a fine. Non-punitive remedies can be sought under s 246.

A displayed price includes one printed on or affixed to the goods or their packaging, or displayed with the goods, or included in an advertisement for the goods.

In addition to these provisions, s 48 requires that where goods or services of a kind that are ordinarily acquired for personal, domestic or household use or consumption are supplied, and the price of the component parts of these goods or services are displayed separately, the single price for the goods or services must also be prominently displayed (excluding the cost of delivery). The single price is the minimum price of the goods or services including all charges and taxes payable.
