Dataset
Allsupers Research publishes a monthly sample of UK supermarket prices as a CSV file. Each snapshot captures prices at the end of the stated day (Europe/Amsterdam time). The sample follows the ONS shopping-basket structure and is intended for journalism, research and public analysis.
Most recent snapshot

Each row carries the ONS category, product name, brand, retailer, price, currency, measurement date, package size and unit, on-offer flag, price per kg/l, match tier (exact, equivalent or similar) and cluster ID. The first two lines of the CSV start with `#` and describe the methodology and license.
