Woolworths & Coles Scraper: Australian Grocery Prices

Australia's two biggest supermarkets in one run, with the same product matched across both. Search as you would on the store website and get one row per product per store:

• The product: name, brand, pack size, category, image, product URL, barcode (Woolworths)
• The price: shelf price, was-price, savings, on special flag and the promotion text
• Unit price: price per 100 g / 1 L as the store shows it, plus the number
• Availability: in stock or not
• Cross-store match: the same branded product at the other chain, its price, cheaperAt and priceDifference

Store brands (Woolworths, Coles, Macro...) are never paired, because they are different products.

Uses

• Price comparison apps and sites: Woolworths vs Coles for the same branded product
• Specials and catalogue tracking: schedule weekly and catch every half-price and special
• Brand and category managers: your shelf price, unit price and promotions at both chains
• Inflation and basket research: track a fixed basket over time
• Pair it with Food Product Data Scraper for ingredients and nutrition by barcode

Notes

• Prices are the stores' default online prices; store-specific in-store prices can differ.
• Woolworths pages hold 36 products and Coles pages 48; the limit applies per store.
• Matching needs the same pack size and a near-identical name, so some genuine pairs are missed rather than mismatched.

Pricing

• $0.0015 per product row, cross-store match included
• No start fee. Filtered-out rows are free.
