New Price Pulse: ice cream and cola up, suncare cut. What the heatwave did to your shopBasketWatch tracks grocery prices across SuperValu, Tesco, Dunnes Stores and Aldi. The full catalogue is refreshed daily across all four retailers, capturing every SKU, every shelf price and every promotion and price increase as it happens, and building a historical grocery price record day by day. SKU, price, unit price, promotion and category data delivered as a clean API and catalogue export.
Live coverage
Below is a live sample from the latest BasketWatch refresh — 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 every SKU.
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 refreshes the full catalogue, prices and promotions daily across all four retailers, so you can see exactly how Irish grocery is discounting — by SKU, by category and by date.
"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.
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 or Dunnes 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.

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 and Aldi, then keeps each day as a snapshot, so you can see exactly how grocery prices in Ireland move over time.
Every product is checked daily across all four retailers, capturing the shelf price, unit price and promotion, and keeping each day 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.
