subscriptionsPurchase options and subscriptions (ucp#890, merged to the UCP spec's main branch on 10 Nov 2026 and planned for the 2026-12-08 release): some products can be bought once or on a plan. Sunflowers every two weeks for 10% less, peonies monthly for 15% less, Letterbox Flowers monthly with the first box half price or as a three-month gift that ends on its own, and Office Weekly Flowers only as a weekly subscription. Each subscription line carries its schedule, a subscription policy and a disclosure, and the order keeps the option as it was agreed. An agent whose profile does not declare the extension buys everything once, and never sees the subscription-only item. Responses in 2026-04-08 leave it out. on flowers-subscriptions.ucpsandbox.com.
