New Lidl is now tracked: Lidl's online prices for its Tallaght store, compared with the other fourBasketWatch tracks grocery prices across SuperValu, Tesco, Dunnes Stores, Aldi and Lidl. We record the products each chain lists online, with shelf prices and promotions, checked every morning, and build a historical grocery price record day by day, with dated snapshots and a public log of data corrections. SKU, price, unit price, promotion and category data, plus barcodes, ingredients and per 100g nutrition, delivered as a clean API and catalogue export.
Independent. Not affiliated with, endorsed by or sponsored by any retailer, and no shop or brand pays to appear or to rank higher. Retailer and brand names belong to their owners and are used only to identify the prices compared.
Latest collection
Below is a sample from our latest collection: a cross-retailer price comparison on a single SKU, plus rotating promotions pulled straight from the data feed.
What's in the feed
Start with raw SKU coverage, then layer on daily 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 each product we record.
Daily shelf price refresh for known SKUs, with unit price and unit basis for cost-per-unit comparison.
New products, removed lines and volatile SKUs surfaced automatically: prices, promotions and catalogue movements all picked up daily.
Category summaries and price indices for market-wide benchmarking and trend work.
Promotion intelligence
Shelf price is only half the story. BasketWatch records the products each chain lists online, with their prices and promotions, every day, so you can see how Irish grocery is discounting: by SKU, by category and by date.
"3 for €3", "2 for €4" and bundle deals captured verbatim, on 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.
Excel & Power BI
BasketWatch is a direct API, but teams do not need to write software to use it. Load the feed once with Power Query, then analyse it with normal spreadsheet formulas, pivots and dashboards.
Connect directly to BasketWatch with a customer API key, create retailer tables, and refresh daily prices without rebuilding the workbook.
Pull Tesco, Aldi, SuperValu, Dunnes or Lidl into a refreshable table. Category teams can click Refresh All before a price review.
Reference products by BasketWatch ID, product name, brand or category after the table is loaded. No per-cell API calls.
Use the same API key and endpoints in Power BI for category dashboards, promotion tracking and competitor price monitoring.

BasketWatch is built as a decision-support dataset. Every figure is collected, normalised and run through automated data quality checks for accuracy and consistency before it reaches you. We keep coverage current and useful, and we are upfront that online retailer data and source permissions can change.

A consistent, decision-ready feed via API or spreadsheet export.
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.

Grocery price tracking
BasketWatch is a grocery price tracker for Ireland. Every day it records the shelf price, unit price and promotion for tens of thousands of products across Tesco, Dunnes Stores, SuperValu, Aldi and Lidl, then keeps each day as a snapshot, so you can see exactly how grocery prices in Ireland move over time.
We collect prices every morning, Irish time, and check Tesco and SuperValu again later in the morning. Each day's shelf prices, unit prices and promotions are kept as a snapshot of Irish grocery prices.
BasketWatch surfaces grocery price increases and decreases the day after they land, with promotions, was-prices and multibuy deals captured separately so a genuine increase is never hidden by an expiring offer.
Each daily snapshot builds a historical grocery price record for Ireland: look up a product's price history, compare a category over months, or export the back catalogue as a CSV download or JSON API.
Per 100g nutrition (energy, fat, carbs, sugar, protein, salt), full ingredient lists and GTIN barcodes, matched across retailers, so you can look any product up by barcode and compare like for like.
