What this measures — read before quoting
The benchmark is Lowtein's own median across every Australian retailer we track — not a government series. The deals are the best advertised prices Lowtein observed in store flyers this week — deal prices, not average shelf prices. The gap between them measures how good this week's deals are, not how prices are moving. Full method: how we check.
