Coles vs Woolworths: Which Supermarket Is Cheaper in 2026?

Wondering whether to shop at Coles or Woolworths? We break down the real price differences, where Aldi fits in, and how to actually save money on your weekly shop.

Here's the honest answer: neither Coles nor Woolworths is always cheaper. Without specials, their prices are almost identical — usually within 1–2% on a standard basket. The real savings come from knowing when to shop, what to buy as home brand, and when Aldi is worth the detour.

Here's what the research actually shows.

Coles vs Woolworths: Are the prices really different?

For everyday items with no specials on, Coles and Woolworths charge almost the same. Independent testing by Choice found basket costs at the two major chains differ by less than 2% in most quarters. That's a couple of dollars on a $100 shop — not enough to make one a clear winner over the other.

So if you've been driving across town to save money at one over the other, you're probably not saving much.

Where things get interesting is weekly specials.

Weekly specials are where the real savings are

Both Coles and Woolworths run half-price specials every week, and these rotate. An item that's $6 at Woolworths this week might be $3 at Coles next week. The gap between the two stores opens up significantly when you factor in specials — and a shopper who plans around them can cut 10–20% off their total bill.

The strategy most savvy shoppers use:

  • Check both stores' specials before heading out
  • Stock up on pantry staples when they hit half price
  • Mix and match between the two depending on the week

This is exactly the kind of comparison Grocero is built to make easy.

Where does Aldi fit in?

Aldi is the clear winner on everyday prices. A full family shop at Aldi typically costs 25–30% less than the equivalent at Coles or Woolworths. That's not a small margin.

The trade-off is range. Aldi stocks around 1,400 products versus 30,000–40,000 at the majors. You won't find every brand you're used to, and the range changes weekly with "Aldi Finds" taking up aisle space. For basics — bread, milk, pasta, eggs, canned goods, cleaning supplies — Aldi is almost always cheaper.

A practical approach many families use: do a monthly Aldi run for staples, then top up at Coles or Woolworths for the rest.

Home brand vs name brand: a bigger difference than store vs store

Switching from branded products to home brand (Coles' own range or Woolworths' Essentials) can cut your grocery bill by up to 55% on equivalent items. That's a far bigger saving than choosing Coles over Woolworths or vice versa.

For things like:

  • Tinned tomatoes, pasta, rice, flour
  • Cleaning products, bin bags, paper towels
  • Basic dairy (milk, butter, cheese)

...the home brand versions are usually comparable in quality and significantly cheaper. Where brand matters to you — coffee, certain snacks, specific products — you can keep buying branded. But swapping even half your basket to home brand will show up on your receipt.

So which supermarket should you shop at?

There's no single right answer, but here's a practical guide:

For most Australian households, the best approach is a mix: Aldi for staples, one of the majors for specials and fresh items.

Tips to actually save money on your weekly shop

  1. Check the weekly catalogue before you shop. Both Coles and Woolworths publish their specials online each Wednesday. A five-minute check can save you $15–20.
  1. Buy home brand for basics. You'll rarely notice the difference on staples, and the savings add up fast.
  1. Don't buy perishables in bulk. Buying more than you'll use before it spoils wastes the "savings."
  1. Click-and-collect reduces impulse buys. Ordering online and picking up means you're not walking past displays designed to get you to spend more.
  1. Use a price comparison app. Tracking prices across stores — especially for items you buy every week — takes the guesswork out of where to shop.

The bottom line

Coles and Woolworths are priced almost identically on standard items. Aldi is consistently cheaper for a full basket. The biggest savings at Coles and Woolworths come from using weekly specials and switching to home brand where it makes sense.

Rather than being loyal to one store, the smartest approach is to let the prices decide where you shop each week.
