Who runs Dealwatch, and what it tracks
Dealwatch is an independent project, not a retailer, marketplace or price-comparison network affiliated with any store. It automatically tracks catalogue and product pages across 13 Australian retailers: Kmart, Big W, Officeworks, Target, JB Hi-Fi, The Good Guys, Myer, Supercheap Auto, Sephora, Chemist Warehouse, Booktopia, QBD Books and IKEA. Coverage and category depth vary by retailer, depending on what each store's own website makes available to check automatically.
How often data refreshes
Price checks are scheduled roughly hourly for many retailers, with less frequent checks for some product details. Coverage varies and updates can be delayed, so a schedule does not mean every listing was checked in the last hour. Use each listing's displayed check date to judge freshness.
How "AI-suggested similar products" works
Each product's title, brand and category text is converted into a numeric fingerprint (a sentence embedding, computed with an open-source model running on Dealwatch's own infrastructure — nothing is sent to a third-party AI service) and the suggestions shown on a product page are simply the closest fingerprints in the catalogue by that measure. It is not based on your browsing activity, on what other shoppers looked at, or on price, and it does not know whether a suggested item is cheaper, pricier or currently in stock. Read it as "described in similar terms," not as a personal recommendation.
What we record
Dealwatch records product prices, retailer-listed RRPs where available, and the time a listing was checked. A product’s timeline begins when Dealwatch first records it; “lowest recorded price” means the lowest price in that recorded history, not necessarily the lowest price ever offered anywhere.
Price history on deal cards
Each homepage deal card shows a compact view of the last 30 days, using the last recorded price for each UTC day. The line steps between recorded prices; it is not a prediction. When an earlier price is known, we carry it into the start of the window. Gaps before tracking began stay blank. Daily summaries can omit changes within a day, and the full product page provides more detail. A flat line means no change among the prices shown; a discount can still be measured against an RRP or a higher price from the separate 90-day comparison period.
“History building” means there are not enough points for a chart. History can also be temporarily unavailable without affecting the listed price. “30-day low” refers to our recorded data, not an all-time or market-wide lowest price.
How categories are chosen
We use retailer-supplied categories where available, validated book identifiers and product-title rules. Clear retailer departments take priority over incidental words in a title. Mixed departments and titles can still be ambiguous, so categories may occasionally be wrong. You can report a correction through our Contact page.
How we describe a discount
Every deal identifies its comparison source. “Retailer RRP” means the retailer supplied a recommended or previous price. “90-day price high” means Dealwatch compares the current price with the highest recorded price for that listing during the last 90 days. Marketplace products are labelled because the seller may be a third party.
Retailer comparisons
“Compare the same barcode” matches equivalent valid GTIN/EAN/UPC identifiers supplied by retailers, including versions written with leading zeroes. We check barcode length and check digits before treating a match as exact. A barcode match is evidence from the listings, not a guarantee that retailer data is correct. Check size, colour, pack, seller, stock and delivery before buying.
The comparison shows recorded item prices and check dates. Prices checked within 36 hours are eligible for savings comparisons; older matches are kept separately for reference. “Lowest listed here” only compares the recent listings shown, including clearly labelled marketplace listings, and excludes delivery costs. It is not a claim to cover every retailer or seller.
Model-code and similar-listing suggestions appear separately. They can refer to different variants, so Dealwatch does not calculate savings against them.
Freshness and coverage
Prices and availability can change quickly. Dealwatch shows the last check time where data is available and hides retailer listings that are too old from the main deal feed. Coverage varies by retailer, category and data source; a missing product does not mean it is unavailable or not on sale.
What a deal is not
Dealwatch does not sell products and does not guarantee a retailer will honour a price. Listing errors, short-lived promotions, delivery charges, store-level availability and product variants can affect the final purchase. Always confirm the product, seller, stock and total price on the retailer’s page before buying.
Corrections
If a displayed price or product detail looks wrong, use the “Report an incorrect price” link on that product page. Include the retailer link and a short explanation so we can review the recorded data.
