Woolworths 'marketing magic' trial

The trial in the federal court in Sydney focuses on hundreds of items that were part of Woolworths' 'Prices Dropped' promotion.

Prosecutors used the pricing of Oreo cookies to illustrate how the retailer allegedly contravened its own internal guidelines to trick shoppers.

The watchdog argues that these practices go to the heart of how grocery giants manipulate consumer behavior during a cost-of-living crisis.

Woolworths has defended its marketing methods, though it faces significant fines if found liable for deceptive conduct.
