How to save $100 a week on groceries.
A typical Australian family spends $300–$400 a week on groceries. Trimming a third off without changing what you eat is possible — but only if you stop loyalty-shopping at a single chain.
The cheapest groceries in Australia are split across Coles, Woolworths and Aldi every week, and the prices move. GroceryWise exists to make that split visible at a glance.
- 01
Plan the week around half-price specials, not recipes
Each Wednesday morning, Coles and Woolworths refresh their weekly catalogues and a chunk of the range hits half price. Aldi does the same with Super Savers on Wednesday and Special Buys on Saturday. Open the Coles, Woolworths and Aldi pages on GroceryWise side-by-side and build the week's shopping list from the half-price deals you actually use — pantry staples, freezer stock, household items. A simple grocery budget tracker on the fridge is enough to see the savings compound.
- 02
Split the shop between Aldi and one of the big two
Aldi's everyday pricing on pantry basics, dairy and household items is consistently the cheapest of the three. The fastest grocery price comparison in Australia is also the simplest: do the bulk shop at Aldi for the staples, then top up the half-price specials at Coles or Woolworths. Most families who split their shop this way save $60–$120 a week compared with single-store loyalty.
- 03
Treat the catalogue as a grocery bill calculator
Before you leave the house, build the list against this week's catalogue rather than last week's habits. A good budget meal planner for Australia starts from what's on special, not what you're craving. Two or three swaps a week — chicken for pork because pork is half price, jasmine rice for basmati because basmati is in the Aldi catalogue — adds up to the $100 fast.
- 04
Keep an eye on the Aldi Special Buys window
Aldi Special Buys run a tight Wednesday and Saturday cadence and good stock vanishes by the weekend. GroceryWise refreshes Aldi twice a week so the page is always current — so check Aldi on a Wednesday or Saturday morning if the household needs anything beyond the weekly Aldi staples.
- 05
Buy fresh fruit and veg at the local greengrocer
Fresh produce is the one category none of the big chains reliably wins — a local fruit-and-veg shop is routinely cheaper. In a May 2026 like-for-like basket, the same fruit and veg cost $36.19 at a greengrocer against $56.99 at Coles — about a third less. It's the one step GroceryWise can't scan for you, but greengrocers usually sit in or beside the same shopping centre as the supermarkets, so it stays the one trip.

Frequently asked questions.
Everything you need to know about the best grocery app in Australia for comparing Coles, Woolworths and Aldi.
Is GroceryWise free to use?
Yes. GroceryWise is a free Australian web app — no signup, no install, no premium tier. Open the site, pick a retailer, see this week's specials.Where do you get your specials from?
Directly from each retailer's publicly published weekly catalogue. We pull Coles and Woolworths in every Wednesday morning AEST, and Aldi on both Wednesday and Saturday mornings to capture the mid-week Special Buys drop. See the methodology page for the full data pipeline.Does this work for online shopping?
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.Is my data safe?
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.When will the AI shopper launch?
In development, 3–6 months out. Sign up for the weekly half-price digest to be the first to hear when it goes live.
