What you get

One row per product, in the same fields for both stores:

Data	Woolworths (by search term)	Aldi (by category)
Product	name, brand, pack size, stock code, barcode (EAN)	name, brand, pack size, SKU
Price	price, was price, savings, special flag, promotion label ("Save $0.50")	price, and was price and savings when Aldi shows them
Unit price	as shown ("$2.10 / 1L"), plus pricePerKg, pricePerLitre or pricePerItem	as shown ("$24.95 per 1 kg"), plus the same converted fields
Category	department and category	category path
Health	Health Star Rating, allergens; optionally ingredients and the nutrition panel (per 100 g/mL and per serve)	–
Other	online stock, customer rating, sponsored flag, image, link	image, link
Changes	with a monitor ID: new product, previous price, change in dollars and percent	the same

Each product appears once per run, even when Woolworths repeats sponsored products on every page or a product matches several search terms.

The cheapest per unit, for every search term. Each run reports the cheapest matching product at each store, in the run summary and the log. A real four-item basket, run on 29 October 2026 (465 products read in 39 seconds, 155 delivered):

Search term	Cheapest at Woolworths	Cheapest at Aldi
full cream milk 2l	$1.70/L: Woolworths Full Cream Milk 2L, $3.40	$1.70/L: Full Cream Milk 2L, $3.39
free range eggs	$9.60/kg: Woolworths 12 Pack X Large Free Range Eggs 700g, $6.70	$8.80/kg: Free Range Eggs 700g, $6.19
white bread	$3.80/kg: Woolworths White Sandwich Bread Loaf 650g, $2.50	$3.70/kg: White Sandwich Sliced Bread 650g, $2.39
greek yoghurt	$4.20/kg: Woolworths Natural Greek Style Yoghurt 1kg, $4.20	$3.90/kg: Light Greek Style Natural Yogurt 1kg, $3.89

Prices change every week; these are a snapshot.

Who it's for

• Shoppers, budgeting apps and comparison sites: compare a basket across Woolworths and Aldi on unit price, not just shelf price.
• Brands and category managers: track your products' and competitors' shelf prices, specials and promotions week by week.
• Analysts and journalists: follow grocery inflation on a fixed list of products, with history from scheduled runs.
• Deal hunters: get alerts when products go on special or drop in price.

How much does it cost?

You pay $0.80 per 1,000 products delivered ($0.0008 each), plus Apify's standard run start fee.

Example	Products	Cost
The pre-filled example: full cream milk 2L at both stores (a test run)	17	about $0.01
The four-item basket above	155	about $0.12
Any 1,000 products	1,000	$0.80

A weekly 50-product basket on monitoring costs $0.04 for the first run; later runs cost only for the products that changed.

Free:

• products removed by your filters;
• repeats, such as sponsored products shown on every page;
• with a monitor ID, products whose price and special haven't changed;
• a store that blocks the run delivers nothing and costs nothing.

Set a maximum cost per run in the run options. The run stops cleanly at that amount.

How to use it

1. Add search terms: the products you want, e.g. full cream milk 2l, free range eggs 12, coffee beans 1kg. Woolworths is searched for each one.
2. Pick Aldi categories: the categories those products are in, e.g. Dairy, Eggs & Fridge, or paste a narrower category link from aldi.com.au, such as the Milk category. With search terms set, Aldi products are kept only when their name or brand contains every word of a term.
3. Set options (optional): specials only; the Woolworths order (relevance, price, unit price or name), which decides which products fall within the limit; limits per search and per category; nutrition.
4. For price alerts, add a Monitor ID and schedule the Actor daily or weekly in Apify Console.
5. Click Start. The Products view shows images, prices, unit prices and links; Price changes is for monitoring. Export as JSON, CSV or Excel.

Example output

A real Woolworths row, saved on 29 October 2026:

{

  "searchedFor": "full cream milk 2l"
}

An Aldi row has the same fields (shortened):

{
  "store": "aldi",
  "productId": "000000000000281811",
  "name": "Triple Cream Brie Cheese 200g",
  "brand": "EMPORIUM SELECTION",
  "size": "200 g",
  "price": 4.99,
  "unitPriceLabel": "$24.95 per 1 kg",
  "pricePerKg": 24.95,
  "category": "Dairy, Eggs & Fridge > Cheese",
  "url": "https://www.aldi.com.au/product/emporium-selection-triple-cream-brie-cheese-200g-000000000000281811",
  "searchedFor": "category: Dairy, Eggs & Fridge; matches: brie"
}

Aldi rows have no barcode, stock or nutrition, because Aldi's listings don't publish them.

About the fields

• With a monitor ID, rows also carry isNew and priceChange: { previousPrice, change, changePercent, previousOnSpecial, previousSeenAt }, or null when unchanged.
• Dataset views: Products (images, prices, unit prices and links) and Price changes (for monitoring).
• Run summary: the RUN_SUMMARY record in the key-value store has the totals listed per search and category; products read and delivered; repeats skipped and products filtered out; new products and price changes; and cheapestByUnitPrice, the cheapest matching product per store for each search term.

How the unit-price comparison works

Each store states its unit price for a different measure: Woolworths says "$1.50 / 100G", Aldi says "$24.95 per 1 kg". The Actor converts both into pricePerKg, pricePerLitre or pricePerItem. For each search term, it compares the products that actually match the term's words, using the unit most of them are priced in. Products priced by something else, such as a bunch, keep the store's label, and their converted fields are empty.

Word matching ignores case and word order, and treats the stores' different spellings as the same (Woolworths writes "Yoghurt", Aldi "Yogurt").

Integrations

• Schedules: run it daily or weekly in Apify Console. With a monitor ID, each run returns only price changes.
• Apify API: start runs and read the products as JSON from your own code, with Apify's API or its JavaScript and Python clients.
• Webhooks: call your own endpoint when a run finishes, for example to update a price page.
• Make, Zapier and n8n: send specials and price drops to Slack, email or a spreadsheet with Apify's apps for these tools.
• Monitoring: Apify's monitoring can alert you when a scheduled run fails or returns fewer results than usual.

FAQ

Is it legal to use?

Both supermarkets' website terms restrict automated access and reuse of their data. Woolworths' terms bar robots and other tools that retrieve or index the site. Aldi's bar automated access and reselling or exploiting its data. The Actor uses no evasion: it reads only paths their robots.txt allows, at a polite pace, and stops at block pages. Make sure your use is appropriate; if in doubt, get legal advice.

Why isn't Coles included?

Coles' site blocks automated requests, and this Actor doesn't try to get past blocks.

Why is Aldi read by category?

Aldi's robots.txt closes its search page to automated access, so this Actor uses categories. Smaller categories mean fewer pages: 30 products per page, and about 3,300 products in Aldi's whole range in October 2026.

Are these the prices in my local store?

They are the stores' online listings. Woolworths shows its default online store's prices; in-store prices can differ. Aldi's listings show its everyday prices; Aldi doesn't sell groceries online.

Why does "Specials only" drop Aldi's Lower Prices?

Specials come from each store's own flags and "was" prices. Aldi's "Lower Prices" category lists permanent price cuts with no "was" price, so turn "Specials only" off for it.

Can I track specific products?

Use precise search terms (brand, product and size, e.g. dairy farmers full cream milk 2l) with a low "Most products per Woolworths search". For Aldi, use a narrow category link, and keep the search-term filter on.

Why do Woolworths results include unrelated products?

Woolworths' search is broad and includes sponsored placements. Those rows are marked sponsored, and the cheapest-per-unit comparison only counts products whose name contains your words.

Why is the cheapest "coffee" a coffee creamer?

A product counts as a match when its name contains every word of your term, so a one-word term matches many kinds of product. Use specific terms, such as instant coffee 200g or coffee beans 1kg.

What if a store slows down or blocks the run?

The Actor reads one page a second per store. If a store asks it to slow down, it waits and retries. If a store blocks it, that store is skipped, the other store is still read, and the run summary says what happened.
