Contains the implementation of a shipping calculator given a file of transactions and returning the list with the applied discounts.
The discount follow these rules:
- All S shipments should always match the lowest S package price among the providers.
- The third L shipment via LP should be free, but only once a calendar month.
- Accumulated discounts cannot exceed 10 € in a calendar month. If there are not enough funds to fully cover a discount this calendar month, it should be covered partially.
Prices are included in the code.
