ALDI vs Coles prices: Special Buys vs everyday unit price

What ALDI vs Coles prices actually asks

Shoppers searching ALDI vs Coles prices are usually weighing two different habits. ALDI Special Buys are short runs that rotate hard. Coles specials can shout huge percentage badges on branded lines. Everyday unit price is how you size the staples you buy every week when pack sizes differ.

We make Discount Trolley, so the bias is obvious. Free covers current prices, search, product pages, ordinary unit prices, Today's deals, community browsing and one shopping list. Premium adds live cross-store comparison, barcode and QR scanning, price history, comparative unit-price insight, Smart Swap, spending insights, seasonal context, dark theme and online-shopping links. Coverage is Woolworths, Coles, ALDI and Priceline where data is available. Chemist Warehouse is not covered. We are not affiliated with those retailers, and no app should promise the shelf always matches the screen.

This post is not a national cheapest-chain crown. It walks named Discount Trolley screens: loud Coles deals on Today's Best Deals, a Compare Stores row that shows when a Coles special is missing at ALDI, and a Free unit-price read on a staple pack. For a Coles versus Woolworths walkthrough, read the Coles vs Woolworths prices post. For a Woolworths versus Coles basket angle, read Woolworths vs Coles for your basket.

• You mix ALDI Special Buys with Coles staples some weeks.
• You want unit price on everyday sizes, not vibes about which chain wins.
• You treat a percentage badge as a claim to check, including whether ALDI even stocks that SKU.

Coles specials can shout. That is not the same as an ALDI win.

On Today's Best Deals in mid September 2026, Discount Trolley showed two Coles lines with loud badges. Beach Road Naturals Paw Paw Extract sat at $1.00 was $10.00 with a $9.00 saving badge and 90% OFF. Oral B Pro100 Cross Action Electric Toothbrush sat at $8.00 was $56.00 with a $48.00 saving badge and 86% OFF.

Those are real Coles specials from that screen. They are not proof that Coles beat ALDI on your basket, and they are not a household saving promise. Special Buys and Coles catalogue shout both reward the shopper who asks a boring second question: is this the same product, the same size, and is it even stocked where I shop?

Free Today's deals and ordinary unit prices get you the first pass. Premium is where live cross-store comparison sits when you want Coles, ALDI, Woolworths and Priceline on one product page where data is available.

• Read current price and was-price together.
• Do not crown a chain from two Coles deal cards.
• Ask whether ALDI even carries that SKU before you detour.

When Compare Stores says not available at ALDI

On the Oral B Pro100 Cross Action Electric Toothbrush Black product page, Discount Trolley showed Coles at $8.00 was $56.00 with a $48.00 saving badge and 86% OFF, plus unit price $8.00 per ea. The Compare Stores row said not available at ALDI or Priceline, with limited availability and no Coles store selected yet.

That is the ALDI vs Coles prices trap on same-SKU theatre. A Coles special can look unbeatable while ALDI simply does not stock that line. Special Buys will not magically fill a missing SKU either. Premium live cross-store comparison is where you see the miss without opening three retailer apps.

We are not inventing a saving from that screenshot. Your suburb and your store decide the number. Confirm on the shelf before you buy.

• Use Premium Compare Stores when a Coles special needs an ALDI check.
• Read limited availability before you drive for a percentage badge.
• If ALDI does not stock it, judge a different size or brand on unit price instead.

Everyday unit price still sizes the staples Special Buys leave behind

Special Buys are great when the limited run matches something you need. They are a weak plan for the milk, shampoo and pantry lines you buy most weeks. Everyday unit price is the Free habit that still works when ALDI and Coles pack sizes disagree.

On a Pantene Pro-V Smooth & Sleek Shampoo for Frizzy Hair 375mL product page, Discount Trolley showed Woolworths at $10.00 and unit price $2.67 per 100mL. That unit price is Free. The same screen also showed Woolworths Sydney Metcentre Metro did not stock it, while 35 other Woolworths stores did, plus a note that Metro prices may increase versus standard Woolworths.

Use that same $ per 100mL read when you size an ALDI private-label bottle against a Coles branded pack. Free covers ordinary unit prices on product pages. Premium adds comparative unit-price insight and live cross-store comparison when you want store totals for the full basket.

• Read $ per 100mL or $ per 100g before pack size theatre wins.
• Treat Special Buys as optional extras, not the whole weekly plan.
• Check stock notes before you trust a ticket from any chain.

How to run an ALDI vs Coles prices check before you shop

Put the staples you actually buy into Discount Trolley Free. Read ordinary unit prices. Open Today's deals for loud Coles specials. If you have Premium, run Compare Stores on anything that looks theatrical and note when ALDI is missing.

On one My List screen in mid September 2026, Discount Trolley showed a $15.25 total and a $57.00 savings badge with Woolworths (1), Coles (2) and ALDI (0). Coles carried Beach Road Naturals Paw Paw Extract Natural Hand Wash at $1.00 was $10.00. Woolworths carried a Minions Fleece Throw Rug at $6.25 marked Unavailable and Out of stock. ALDI (0) on that list means those lines did not land at ALDI for that trolley. That is useful data, not a national ranking.

When store totals disagree, decide with trip cost. For a wider ALDI, Coles and Woolworths overview, read Woolworths vs Coles vs ALDI. For the split-shop decision, see whether you should split your grocery shop across two stores.

1. List the real staples on Free.
2. Read unit prices before Special Buys or Coles badges win the week.
3. Use Premium Compare Stores when ALDI availability is the question.
4. Confirm on the shelf.
