The total price of a product or service, including tax, must be shown on marketing. If an accurate price cannot be given, for instance in the case of certain services, then the marketing materials must explain the ways in which the price is calculated.
If a business markets its products using sales prices, then it must also indicate the unit prices of the goods.
The unit price is the price per kilogram, litre, metre, square metre or cubic metre. The unit price must also include value-added tax and other charges, although not any deposits to be paid on the product. The unit price may be used by the consumer to compare the prices of packages of different sizes.
The unit price is usually given by weight (kilograms) or volume (litres). It is calculated based on the net content of the package. The weight of loose goods sold by weight may not include the weight of any packaging.
Marketplace sales may continue using the traditional method of selling solid goods (berries, fruit, vegetables, etc.) by volume (e.g. by litre). This does not apply to industrial products such as sweets.
