For each delivery day and each order module in the cart, Sprwt takes the active bag types that (a) allow that module, (b) are ticked for the chosen pickup location or delivery route, and fills them: each bag takes up to Max Meals items (reduced when meals use containers with a Slot Size above 1). It keeps adding bags of the eligible types until every item is packed. Every bag added charges its Price; the One Time Fee is added only if the customer has never received that bag type before and it is not already in the cart. If no bag type is eligible for the module and fulfilment method, no bags or fees are added.
