Australian Supermarket Prices: Coles, Woolworths & ALDI

What does Australian Supermarket Prices do?

Search Coles, Woolworths and ALDI Australia at the same time and get every product as a clean row:

• Price, was price, saving and the special (1/2 price, multibuy like "Pick any 2 for $7", price drops)
• Unit price as each store shows it, plus a normalized price per kg, per L or per each so you can compare stores fairly
• Barcode (Woolworths), size, brand, category, stock, product link and image
• A free cheapest-store comparison for every search term

Use it for grocery price comparison, price monitoring, specials tracking, market research and retail analytics.

Why this one?

• 3 supermarkets in one run. No need to run and merge three different tools.
• Reliable. Each store gets the connection that works best for it, and the tool switches automatically if one gets blocked. Every request retries on its own. If one store is slow, the other two still finish.
• Accurate. In our tests, unit prices matched price divided by pack size on 800+ products, and prices matched each store's own product page. Products sold by weight are labelled clearly (priceUnit: "per kg" or "each (estimated by weight)").
• Fair billing. You pay only for products saved. Products with no price, unavailable products (unless you ask for them), Woolworths marketplace items and unrelated "filler" products are skipped and not charged.
• Fast small runs. Ideal for apps and AI agents that look up a few products at a time.

How much does it cost?

You pay per product saved. Check the Pricing tab for the current price. The comparison is free.

Cheapest-store comparison (free, in the COMPARISON record):

{ "searchTerm": "milk", "comparedPer": "L", "cheapestStore": "ALDI",
  "stores": [ { "store": "ALDI", "pricePerUnit": 1.59, "name": "Regular Soy Milk 1L", "price": 1.59 },
              { "store": "Woolworths", "pricePerUnit": 1.65, "name": "Woolworths Full Cream Milk 3L", "price": 4.95 } ] }

Good to know

• Price sorts show products named after your search first (a "coffee" search opens with coffee, not with the cheapest tea bags), cheapest first. For unit price, products are compared on the same unit (per L for milk, per kg for cheese).
• ALDI sells these products in store, not online. Prices are ALDI's listed in-store prices.
• Prices are the stores' standard online prices. Some products can cost a little more or less in a specific store.
• Products sold by weight (meat, fruit, deli): Woolworths and ALDI show the price per kg; Coles shows an estimated price per piece plus the price per kg.

Use cases

• Price comparison apps and websites
• Price monitoring: schedule daily runs and track specials and price changes
• Market and retail research: compare brands, sizes and value across Australia's big supermarkets
• AI agents: look up current grocery prices by API
