According to court documents, the watchdog claims Coles:
- Raised the price of products for a short period;
- Then reduced the price from the inflated level;
- Marketed the new price as a significant discount;
- Sold tens of millions of these items, generating "significant revenue".
Among the 245 products cited in the case are everyday staples including Arnott's Shapes, Cadbury chocolates, Colgate toothpaste, Kellogg's snack bars, Palmolive shampoo, Weet-Bix cereal, Maggi noodles and Whiskas cat food.
When announcing the legal action in September 2024, Cass-Gottlieb alleged the conduct was not merely incidental but deliberate.
"We also allege that in many cases both Woolworths and Coles had already planned to later place the products on a Prices Dropped or Down Down promotion before the price spike, and implemented the temporary price spike for the purpose of establishing a higher 'was' price," she said at the time.
A parallel case has also been launched against Woolworths Group over similar "Prices Dropped" campaigns.
