PRESS RELEASE: New Data Shows Sticking to One Supermarket Costs the Average Family $3,900 a Year.

A groundbreaking data analysis has revealed the staggering “loyalty tax” Australian families are paying by sticking to a single supermarket, with new figures showing the habit costs an average of $3,900 per household annually.

The report, based on pricing data from the comparison tool Grocerize.com.au, directly challenges the value of supermarket loyalty programs and proves that shopping strategically is vastly more profitable for consumers.
The analysis exposes the financial fallacy of loyalty, where the minor rewards offered by points-based systems are dwarfed by the significant, immediate cash savings available by comparing prices. While a shopper might need to spend $2,000 to earn a $10 voucher through a typical loyalty program, that’s a 0.5% saving, Grocerize data shows that the average family user saved 28% on average on their weekly shop by splitting their shop between Coles and Woolworths.

This “loyalty tax” is the calculated difference between the cost of a typical family’s weekly basket at one store versus the cost of the same basket optimised for the lowest price on every item.

“The data is clear: brand loyalty is the most expensive habit a grocery shopper can have,” says Blake Bennett, founder of Grocerize, the tool that compiled the data. “Supermarkets have spent decades and billions of dollars cultivating loyalty, but our data shows the real loyalty should be to your own budget. We built Grocerize to show people the raw numbers, proving that the biggest savings don’t come from a points card; they come from information.”

The analysis highlights that while one store might be cheaper for some items, the other is almost always cheaper for others on the same day. Sticking to one retailer means knowingly overpaying for a significant portion of your basket.

“Consumers are conditioned to value points, but they are a poor substitute for actual cash savings,” says Catherine Reeve, a (hypothetical) Consumer Finance Advocate. “A $3,900 annual saving is enough to cover a household’s electricity bill for a year or fund a family holiday. This data proves that the most financially sound strategy is to be a supermarket ‘free agent,’ guided by price, not by habit.”

The Grocerize platform works by allowing shoppers to see these discrepancies in real-time, empowering them to:
Identify the true cost of their basket at both major retailers. Pinpoint which specific items are driving up their bill at their “preferred” store.
Make an informed choice to switch stores or split their shop for maximum savings.

“We encourage every Australian family to challenge their own habits,” Bennett urges. “Before your next shop, ask yourself: is my loyalty costing me a fortune? The data shows that for millions of us, the answer is yes.”
