Weekly Irish grocery data feed
BasketWatch monitors SuperValu, Tesco, Dunnes Stores and Aldi every week, then packages SKU, price, unit price, promotion and category signals into a clean API and catalogue export.
Coverage
BasketWatch tracks product ranges, shelf and unit prices, pack sizes, category paths and week-on-week price movement across the four supermarkets Irish shoppers compare.
Broad national range, built for category benchmarking and promotions analysis.
Major multiple with deep own-brand coverage and Clubcard promotional pricing.
Fast-moving range and Simply Better lines, with heavy multibuy and savings activity.
The discounter that sets the price floor across Irish grocery categories.
What's in the feed
Start with raw SKU coverage, then layer on weekly price movement, range alerts and category analytics as your use case grows.
Names, brands, pack sizes, category paths, product URLs and first-seen dates for every SKU.
Weekly shelf price, unit price and unit basis — the full cost-per-unit picture for every SKU.
New products, removed lines and volatile SKUs surfaced automatically every week.
Category summaries and price indices for market-wide benchmarking and trend work.
Promotion intelligence
Shelf price is only half the story. BasketWatch reads the offer mechanics off every retailer each week, so you can see exactly how Irish grocery is discounting — by SKU, by category, by week.
"3 for €3", "2 for €4" and bundle deals captured verbatim — the day each offer goes live on shelf.
"Save €0.75" cuts and half-price flashes across SuperValu and Dunnes, tied to the exact SKU on offer.
The pre-promotion "was" price next to today's price, so real promotional depth is measured, not guessed.
Tesco Clubcard and Real Rewards member pricing, plus the validity window each promotion runs for.
The API
Designed for buyers, suppliers, analysts and software teams who want current Irish grocery data in their own tools, dashboards and models.

]Query one retailer or all four, filter by category, and pull weekly price movement — all from the same key.
The full product catalogue — every SKU with name, brand, shelf price, unit price, pack size, category path, product URL and first/last-seen dates.
Products currently on promotion — the offer label (multibuy, "SAVE €X", "Only €X"), the "was" price, the offer validity window, and Tesco Clubcard prices.
Price changes for a given week — which SKUs moved and by how much, as both a percentage and an absolute amount.
Products newly listed in the last N days — range additions and launches.
Products that have dropped off the catalogue — delistings and range cuts.
The most-repriced SKUs over a window — a price-elasticity and competitive-battleground signal.
Detected shrinkflation — products where the pack shrank or unit price rose while the shelf price held steady.
A per-category roll-up — SKU counts, average price and how much of the category changed.
A category-level price index — track a whole category's price level over time.
A single product — full detail plus its complete price history.
Data notice
BasketWatch is built as a decision-support dataset. We work to keep coverage current and useful, while recognising that online retailer data and source permissions can change.
We endeavour to keep the feed current, complete and accurate, but retailer sites, promotions, availability, product names and pack sizes can change without notice.
Coverage is based on online grocery information that BasketWatch can reasonably collect and supply. Where terms, technical measures or rights-holder requests restrict collection, we may limit, pause, remove or decline affected data.
API and export access is supplied for lawful business analysis only. Customers should not use the feed in a way that breaches applicable terms, intellectual-property rights, database rights or other restrictions attached to source material.
Who uses it
BasketWatch turns online shelf data into an operational feed for commerce, newsrooms, government bodies and research teams that need a defensible weekly view of Irish grocery prices.
Track where competitors sit on shelf price, unit price, promotional activity and category assortment across all four retailers.
Monitor price floors, promotional depth, private-label pressure and product movement against the multiples that matter.
Use weekly grocery data as a reference point for market pricing, indices and buying decisions.
A weekly source-of-truth for cost-of-living coverage, basket comparisons, shrinkflation stories and data journalism — citable, timestamped and consistent across retailers.
Independent grocery price evidence for consumer protection, competition oversight, inflation tracking and official statistics — refreshed weekly with a full audit trail.
For universities, think-tanks and policy researchers studying food prices, household budgets and Irish retail competition — including back-fills for longitudinal work.
