Supermarket Specials in Australia: Where to Find the Best Deals
Find and compare the best supermarket specials in Australia for 2026 — and stop missing deals at Coles, Woolworths, and Aldi.
The best supermarket specials in Australia rotate weekly at Coles and Woolworths — both reset their catalogues every Wednesday, with popular pantry staples cycling on roughly a 4–6 week rotation. Aldi takes a different approach: everyday low prices that are typically 20–30% below the major chains, with "Special Buys" non-grocery deals landing Wednesday and Saturday. The ACCC’s 2024–25 grocery inquiry found some "was/now" deals used inflated reference prices, so knowing a normal price before you buy is worth the effort.
If you’ve ever stood in a supermarket aisle wondering whether that "half price" tag is actually a good deal — you’re not alone. Most Australians shop across multiple stores trying to stretch their grocery budget, but constantly flipping between Woolworths, Coles, and Aldi catalogues gets old fast.
This guide breaks down how each major Australian supermarket runs its specials, what their real strengths are, and how to get the most out of deals without wasting your weekend on it.
How the Big Five Compare at a Glance
Woolworths
Woolworths is Australia’s largest supermarket chain with around 1,000 stores nationally. Their weekly specials — mostly half-price deals on name brands — rotate on a roughly 4–6 week cycle for popular products like pantry staples and personal care items. New specials go live every Wednesday morning, so if you’re a catalogue planner, that’s your day.
Their Everyday Rewards program earns you points on every shop, which convert to dollars off at checkout. It also unlocks personalised discounts based on what you regularly buy — handy if you stick to the same products week to week.
Where Woolworths wins: Sheer range. You can do an entire weekly shop under one roof, and their online store with delivery and click-and-collect is well developed. Half-price deals can be genuinely good value if you stock up when items you use regularly go on sale.
The catch: Base prices on everyday items are higher than Aldi. And the "half price from what price?" question is real — the ACCC has investigated supermarket pricing practices, finding that some "was/now" deals used inflated reference prices. That doesn’t mean every special is dodgy, but it pays to know what something normally costs before assuming 50% off is a bargain.
Coles
Coles and Woolworths are so similar in strategy that most Australians bounce between both, picking whichever has the better specials that week. Same mid-range pricing model, same Wednesday catalogue refresh, comparable product range.
Where Coles differentiates is with Flybuys — arguably the more versatile loyalty program, as points can be redeemed for cash discounts, flights, and partner rewards. Coles also has a reputation for strong fresh produce, particularly their beef and own-brand range.
Where Coles wins: If you’re already a Flybuys member and earning points through Coles Express fuel, the ecosystem locks in well. Their Little World Beverages own-brand range is a genuine quality pick in categories like coffee and snacks.
The catch: Same scrutiny as Woolworths applies on reference pricing. When both chains are running the same item on special the same week, the competition is real — but when they’re not, it’s worth checking.
Aldi
Aldi plays a completely different game. Instead of running rotating half-price specials, they keep their prices low all the time — typically 20–30% cheaper than comparable items at Woolworths or Coles on their core range. There’s no loyalty program, no complicated catalogues to track. You just pay less.
Their weekly specials — released Wednesdays and Saturdays — are the famous "Special Buys" (non-grocery items like tools, clothing, camping gear). These are time-limited and genuinely popular, but they’re a side attraction rather than the main reason to shop there.
Where Aldi wins: Consistent savings without the mental overhead of deal-tracking. Their private-label products have improved significantly and regularly win taste tests against name brands. If you’re comfortable swapping to store brands, your grocery bill will drop noticeably.
The catch: Limited range — roughly 1,800 products compared to 30,000+ at Woolworths. You’ll almost certainly still need to pick up some items elsewhere. And there’s no online shopping, so it’s in-store only.
IGA
IGA is a network of independently owned stores, which means the experience varies more than any other chain. Some IGAs are genuinely excellent local grocers with competitive specials and a strong range; others are smaller convenience-style stores with higher prices.
Weekly specials are coordinated nationally but local stores have flexibility, so deals can differ. You’ll generally find IGA specials refresh on Wednesdays, though this isn’t guaranteed everywhere.
Where IGA wins: Location and convenience. If there’s no Coles or Woolworths nearby, IGA fills that gap. Many stores also stock local or regional products you won’t find at the big chains, and the personal service is typically better. For a mid-week top-up when you just need three things, it’s often the most practical option.
The catch: Base prices tend to run higher than the major chains, and the specials rarely match the depth of Woolworths or Coles deals. For a full weekly shop, you’ll pay more unless you’re strategic.
Costco
Costco is a different category entirely. It’s a members-only warehouse club — you pay an annual fee (currently around $65 for a Gold Star membership) to access bulk products at wholesale prices.
There are no weekly half-price specials in the traditional sense. Instead, Costco runs member-only promotions periodically, and the main draw is consistently low unit prices on large pack sizes. Their Kirkland Signature private label is well-regarded across everything from olive oil to batteries.
Where Costco wins: If you have a large household, storage space, and buy the same products in bulk regularly, the membership pays for itself quickly. Their fuel stations are also genuinely cheaper than most competitors. Unique imported products are a bonus.
The catch: The membership fee is a real upfront cost. Buying in bulk means you need space and cash flow. And it’s not useful for fresh produce or anything you need in small quantities.
How to Actually Get the Best Deals
The honest truth is no single store wins every category every week. The shoppers who save the most tend to:
- Do their main shop at Aldi for pantry staples where brand doesn’t matter
- Check Woolworths and Coles weekly specials for the brands they do care about, and stock up when they go half price
- Use Grocero to search any item and instantly see which of the major stores has the best price right now — without manually opening three different apps or catalogues
Grocero is free, needs no account, and pulls prices from Coles, Woolworths, and Aldi into one place. It’s particularly useful when you’re planning a shop and want to know whether to go to Woolworths or Coles for a specific item this week.
Common Questions
Are Woolworths and Coles half-price deals genuine?
Sometimes yes, sometimes not quite. The ACCC’s 2024 grocery inquiry found that both chains had used inflated reference prices on some "was/now" deals, meaning the "original" price wasn’t always what the item normally sold for. That said, many half-price specials on name brands are legitimate — especially on household staples that rotate on a predictable cycle. The safest approach is to know roughly what you normally pay for things you buy regularly, so you can judge whether a deal is real.
How often does the same item go on special?
For popular products at Woolworths and Coles — things like cereal, pasta, cleaning products, and personal care — the typical rotation is every 4–6 weeks. If something is on half price this week and you use it regularly, it’s generally worth stocking up.
Is Aldi actually that much cheaper?
For the products they carry, yes — typically 20–30% cheaper on like-for-like comparisons. The main limitation is range. You can’t do a complete brand-specific shop there, but for store-brand basics it’s hard to beat.
Does Costco make sense for a regular household?
It depends on your situation. For a family of four or more who can store bulk goods and consistently buys the same products (paper towels, coffee, frozen meals, cleaning supplies), the $65 annual fee pays for itself fairly quickly. For one or two people, it usually doesn’t.
When do specials update each week?
At Woolworths and Coles, new weekly specials go live every Wednesday morning. Aldi’s Special Buys (non-grocery items) land on Wednesday and Saturday. If you’re planning a shop around deals, Wednesday is the day to check catalogues.
Conclusion
Australian supermarkets all have their sweet spot — Woolworths and Coles for variety and rotating deals, Aldi for consistent low prices on the basics, IGA for local convenience, and Costco for bulk value. No single store is cheapest for everything, which is why comparing prices before you shop makes a real difference.
Tools like Grocero take the legwork out of that comparison — one search, prices from all three major chains, no app-switching required. Combined with a bit of knowledge about how deal cycles work, it’s a straightforward way to cut your grocery bill without overhauling how you shop.
