Description
Three bag sizes at the counter. Choose the bag first and the price is settled, then fill it with any mix from the ten sweets on the shelf. A small bag holds six scoops, a medium holds ten, and a large holds sixteen.
Nothing you choose changes the price. That is the whole idea of buying by the bag, and it is why the counter never has to weigh anything twice.
What this example demonstrates: container sizes on a build a box slot. Each size carries its own capacity and its own flat price, the contents are priced at zero, and the shop listing shows the cheapest bag as the from price.
