Field notes
Product entries include item identifiers, package sizes, categories, and a last-checked date; some also show unit pricing, such as cost per 100 g. The comparison panel uses dated records from the same store and filters out items without a matching product and displayed quantity. A product-request control is visible, though the extract does not show how requests are handled.
