This case is a clear pricing lesson for any business that runs discounts, specials, launch offers or was/now campaigns. Customers do not read a price ticket like a lawyer. If the presentation tells them the current price is a real discount from the previous price, the business needs to make sure that impression is true.
The Court focused on whether the previous price had been a real trading price for long enough to make the advertised reduction genuine. The judgment is especially useful because it looks at internal guardrails as well as consumer-facing tickets. Coles had systems designed to manage Down Down promotions, but the Court still had to test whether the sample tickets conveyed a genuine reduction and whether that representation was misleading.
For small businesses, the lesson is practical. Before running a price-drop campaign, keep a record of the old price, how long it was charged, how many sales happened at that price, why the price changed, and how the offer is displayed online or in-store. A temporary price rise followed by a headline discount can create Australian Consumer Law risk even if the arithmetic on the ticket is technically correct.
