rail-and-panel
product cards in a grid beside a sticky panel with the tier rail lit as the count rises, the picks and the total (a bar that opens on a phone): a wide range to pick from; the merchant’s own tiers and prices only
slots
a row of empty places to fill under the tier line, the products below, each pick dropping into the next place: a short, countable bundle (« 3 pièces, −10 % »); the merchant’s own tiers and prices only
