Methodology

Each week's price for a product is the price we had recorded for it on the Sunday of that week, taking the cheapest price across the full-catalogue stores that list it for sale. Only products with a recorded price in both the current and the comparison week are counted as compared. A product only appears in the biggest fallers or risers if its price the week before was at least £1.00, the change was at least 20p, a rise was no more than 90% and a fall no more than 70%, and it is a grocery or household product rather than a book, toy, clothing or electrical item, so that a single unreliable reading cannot headline the report. Within each list, groceries come before household, personal care, health and baby products. A category appears in the movement table only if at least 30 of its products were compared. The basket comparison covers Tesco, Sainsbury's, ASDA and Morrisons, and a category's basket is only the products all four of those stores carried that week, shown only where that basket reaches 20 products. This report is a weekly snapshot: the retailer's own site and the price at the checkout are authoritative.
