The playbook
Save $100 a week at the cheapest supermarket.
A typical Australian family spends $300–$400 a week. Trimming a third off without changing what you eat comes down to four habits.
Read the full playbook →- Shop the specials, not a recipe listBuild the week around what is half price rather than deciding the menu first.
- Split the shopAldi for staples, one of the big two for the rest. Most families save 12–18% on staples alone.
- Compare per 100g, not per packThe bigger box is cheaper roughly half the time. We do the arithmetic on every listing.
- Buy fresh produce at a greengrocerTypically 20–30% under supermarket prices for the same quality.
What we are building next
Three upgrades on the way.
The web app is the foundation. Each of the next three does more of the work for you: telling you when a price moves, costing a whole shop, then building the basket itself.
Price drop alerts
Follow a product and hear from us the Wednesday its price falls at any of the four — instead of checking the catalogue yourself to find out.
A basket optimiser
Put your usual shop in a list and see what it costs at each retailer, item by item, with the cheapest pack size worked out for every line.
An AI grocery shopper
Takes this week's specials from all four retailers and assembles the cheapest possible basket for your household automatically — no more clicking between four sites.

FAQ
Frequently asked questions.
Directly from each retailer's publicly published weekly catalogue, stamped with the date we saw it. We read Coles, Woolworths, Aldi and Chemist Warehouse early Wednesday morning AEST. Aldi publishes its Special Buys drops ahead of time, so that one read covers both the Wednesday and the Saturday drop. We are not paid by any of them and we do not sell anything. See the methodology page for the full data pipeline.
GroceryWise does it, and it is a website rather than a phone app — there is nothing to install and no account to create. Open it in any browser on a phone, tablet or laptop and compare a product across Coles, Woolworths, Aldi and Chemist Warehouse. It is free, and every price is stamped with the date we read it from the retailer's own catalogue.
Search a product or open a category and the two sit side by side, each restated per 100g, per litre or per item so different pack sizes line up. You can also browse either weekly catalogue on its own from the retailer pages. Both catalogues change on Wednesday morning AEST, which is when we re-read them.
Yes. GroceryWise is free, with no signup and no premium tier. Open the site, compare a product across all four supermarkets, or browse this week's specials at any one of them.
Yes for Coles and Woolworths — their weekly catalogue prices generally apply to both in-store and online shops. Aldi is in-store and Special Buys only, because Aldi doesn't run a general online grocery service in Australia.
Every listing is restated per 100g, per litre or per item, so a 500mL bottle and a 2L one can be compared without doing the arithmetic. Where a retailer doesn't publish a pack size we infer it from the product name, still rank it, and mark it est. so you can see which figure is inferred.
There is nothing to share. GroceryWise has no accounts, no shopping history, no personal profile and no third-party trackers beyond standard analytics. The only data we collect is anonymous page-view stats. The newsletter signup is the one optional exception — we send your email to Beehiiv to manage the weekly half-price digest and nothing else.
In development, 3–6 months out. Sign up for the weekly half-price digest to be the first to hear when it goes live.
