Background: Woolworths is one of Australia's two supermarket giants, making up nearly 40% of the national grocery market, compared to Coles at around 30%. And with cost-of-living pressures, both are under pressure to keep grocery prices down. Despite that, Woolies' supermarket sales jumped 4.6% this year.

What happened: Now, anonymous suppliers are coming forward and claiming Woolies is threatening to pull their products from shelves... if they don't agree to lower prices. Woolworths is trying to keep prices low without eating into their own margin at all. They'd rather it eat into the margin of suppliers.

What else: So Woolworths is asking its suppliers to lower their prices... or face being pulled from the shelf. And when you control nearly 40% of the grocery market, that's a pretty powerful negotiating position. Something called range reduction.

What's the key learning?

💡 Range reduction is when a supermarket reduces choice on the shelf for a particular category. It may sound harmless to consumers… but for a supplier, losing your spot on the shelf can basically end the product.

💡 Big supermarkets have serious bargaining power over suppliers. The ACCC found a major bargaining imbalance, leaving many suppliers with nowhere else to go. So "cut your price or get cut" isn't really much of a negotiation.

💡 Private labels can squeeze independent suppliers even further. Coles now stocks around 5,600 "exclusive to Coles" products, up 1,600 in just one year. And every new home-brand product is potentially one less shelf sport for an independent supplier.
