Australian Supermarket Prices: Coles, Woolworths & ALDI in one run

Search Coles, Woolworths and ALDI Australia at the same time and get every matching product with its price, was-price, special flag and unit price, plus a ready-made price comparison that tells you which supermarket is cheapest for each search term.

One run replaces three scrapers. Instead of running a Coles scraper, a Woolworths scraper and an ALDI scraper separately and lining up their different formats yourself, you get one clean dataset with the same fields for every store, and unit prices converted to the same basis (per kg, per litre or each) so they can be compared directly.

This Actor is an independent tool. It is not affiliated with, endorsed by or sponsored by Coles Group, Woolworths Group or ALDI. Store names are used only to describe the public websites the data comes from.

What you get

• Coles prices: shelf price, was price, specials (including "save $x" and multi-buy text), unit price and stock flag from Coles online search.
• Woolworths prices: price, was price, specials, cup (unit) price, barcode and stock status from Woolworths online search.
• ALDI Australia prices: in-store prices, pack size and ALDI's per-unit price, including Special Buys and loose produce sold per kg.
• Grocery price comparison for Australia: one extra row per search term with the cheapest matching product at each store, ranked by unit price, and the percentage saved against the dearest store.
• Same schema for all three chains, so you can chart, filter or join the data without per-store clean-up.
• Fast and light: no browser and no login. A 3-store, 3-term run with 40-60 products per store finishes in under 30 seconds.

Use cases

• Track the cost of a weekly shopping basket across Coles, Woolworths and ALDI
• Grocery price monitoring and inflation research in Australia
• Specials and half-price tracking for deal sites and newsletters
• Competitor pricing and range checks for FMCG brands and suppliers
• Feeding price-comparison apps, spreadsheets, dashboards and AI agents

Example input:

{

  "stores": ["coles", "woolworths", "aldi"],
  "maxItemsPerStore": 50,
  "compare": true
}

Output

Each product is one row (type: "product"):

{
  "type": "product",
  "store": "woolworths",
  "productId": "200695",
  "name": "Weet-Bix Breakfast Cereal 1.2kg",
  "brand": "Weet-Bix",
  "size": "1.2kg",
  "price": 7,
  "wasPrice": null,
  "unitPrice": 0.58,
  "unitOfMeasure": "100G",
  "normalizedUnitPrice": 5.8,
  "normalizedUnit": "kg",
  "isOnSpecial": false,
  "barcode": "9300652010794",
  "inStock": true,
  "url": "https://www.woolworths.com.au/shop/productdetails/200695/weet-bix-breakfast-cereal",
  "imageUrl": "https://cdn1.woolworths.media/content/wowproductimages/large/200695.jpg",
  "searchTerm": "weet-bix",
  "scrapedAt": "2026-10-19T18:37:19.512Z"
}

• price and wasPrice are in AUD. wasPrice is set only when the product is on special with a higher previous price.
• unitPrice and unitOfMeasure are exactly as the store shows them (for example $0.58 per 100G).
• normalizedUnitPrice and normalizedUnit convert that to per kg, per L or each, so Coles, Woolworths and ALDI can be compared directly.
• Coles rows also include specialText (for example save $1.00 or Pick any 2 for $7). Woolworths rows include barcode.

With compare on, each search term also gets one comparison row (type: "comparison"):

{
  "type": "comparison",
  "searchTerm": "full cream milk 2l",
  "comparedPer": "L",
  "cheapestStore": "aldi",
  "cheapestProduct": "Full Cream Milk 3L",
  "cheapestPrice": 4.95,
  "cheapestUnitPrice": 1.65,
  "savingVsMostExpensivePct": 2.9,
  "ranking": [
    { "store": "aldi", "comparableUnitPrice": 1.65 },
    { "store": "coles", "comparableUnitPrice": 1.7 },
    { "store": "woolworths", "comparableUnitPrice": 1.7 }
  ],
  "stores": {
    "coles": { "productId": "439693", "name": "Coles Full Cream Milk 2L", "price": 3.4, "unitPrice": 1.7, "unitOfMeasure": "1l", "comparableUnitPrice": 1.7, "isOnSpecial": false, "matchedProducts": 17 },
    "woolworths": { "productId": "888137", "name": "Woolworths Full Cream Milk 2L", "price": 3.4, "unitPrice": 1.7, "unitOfMeasure": "1L", "comparableUnitPrice": 1.7, "isOnSpecial": false, "matchedProducts": 11 },
    "aldi": { "productId": "000000000000398894", "name": "Full Cream Milk 3L", "price": 4.95, "unitPrice": 1.65, "unitOfMeasure": "1L", "comparableUnitPrice": 1.65, "isOnSpecial": false, "matchedProducts": 7 }
  },
  "scrapedAt": "2026-10-19T18:37:18.379Z"
}

The dataset has two views in the Apify Console: Products and Price comparison. Export either as JSON, CSV, Excel or HTML, or read them through the Apify API.

How the comparison works

1. For each store, products whose name contains every word of your search term are kept (sizes such as 2l are ignored for matching).
2. Products where the term appears near the start of the name are preferred, so a search for bananas compares bananas, not banana bread.
3. The comparison uses the unit most of those products share (per kg, per L or each), and picks the product with the lowest unit price at each store.
4. If a store sells the item in a different unit (for example loose bananas priced each rather than per kg), that store gets a note instead of a misleading price.

Specific search terms give the best comparisons: full cream milk 2l beats milk, and cavendish bananas beats bananas.

Tips and limits

• Prices are the stores' default online prices. Coles and Woolworths prices can differ slightly by state or store; ALDI prices are national in-store prices.
• ALDI's search matches each word separately, so multi-word searches can return extra ALDI products. They stay in the product rows but are filtered out of the comparison.
• Every product found is a row. To keep a run small, lower maxItemsPerStore.
• If one store fails, the others still return data and the run log says which store and term failed.

FAQ

Is this a Coles scraper, a Woolworths scraper and an ALDI scraper in one? Yes. Pick any one, two or all three stores in stores.

Do I need a login, API key or residential proxy? No. The Actor reads the same public search results shoppers see, without logging in. The default Apify datacenter proxy is only used as a fallback.

Can I schedule it? Yes. Use an Apify schedule (for example every Wednesday, when new specials start) to build a price history for your basket.

Is scraping supermarket prices legal? This Actor only collects publicly available product and price information. You are responsible for how you use the data, including any rules that apply in your jurisdiction and the websites' terms.
