It is illegal for competitors to work together to fix prices rather than compete against each other. This conduct restricts competition, and can force prices up and reduce choices for consumers and other businesses.
A supplier may recommend that resellers charge an appropriate price for particular goods or services but may not stop resellers charging or advertising below that price.
While the ACCC can’t set supermarket prices, we do require large supermarkets and online stores to display unit prices to help you compare many products. The Australian Consumer Law also protects you against businesses that make false claims about grocery items.
There are laws about the way prices are displayed. Prices should be genuine and you should be able to easily see the total price of anything advertised. If multiple different prices are displayed on a product or in advertising, the business has to fix the display or sell you the item for the lowest price.
