FAQ

Does search include every supermarket? Search rows are the card: best price, unit price, brand, and pack size. Set mode to product for each supermarket price and the weekly best-price series. Category rows already nest the shops shown on that list.

Is the weekly series one price per supermarket? No. priceHistory is the best price by week on the product page. Each supermarket’s current price is in retailers.

Which retailers can deals use? Asda, Sainsbury's, Morrisons, Co-op, Iceland, Boots, Superdrug, Savers, Amazon, and Ebay. Tesco and the other supermarkets still appear on product and category rows.

What if the keyword matches nothing? The run finishes with an empty dataset. Other keywords in the same input still run.
