list-priceList price (ucp#1016, merged to the UCP spec's main branch on 9 Nov 2026 and planned for the 2026-12-08 release): a few products carry a reference price, shown as a strikethrough, and cart, checkout and order line items carry it as item.list_price. Sunflowers and peonies are on sale (the price they usually sell for is the list price), the White Orchid has a recommended price above ours, and the Ceramic Pot has one below ours, which is no saving. Totals and discounts never include it. Responses in 2026-04-08 leave it out. on flowers-list-price.ucpsandbox.com. The baseline store is flowers.ucpsandbox.com.
