Article 3 Obligation to indicate selling price
Where a person indicates that any goods (being goods other than motor fuel) are or may be for sale by retail, he shall indicate in writing the selling price of those goods in accordance with the following provisions of this Order.
The selling price shall be indicated either—
in the case of goods sold from bulk, by reference either to a unit of measurement or to a single item or to a specified quantity of the goods, or
in the case of other goods, by reference to a single item or to a specified quantity of the goods.
Where the selling prices at which different quantities of goods may be purchased do not vary in the same proportion to each other as the quantity of the goods, the indication of the selling price shall include sufficient information to enable the purchaser to calculate what the selling price of any quantity of the goods is.
