Because train fares in the Netherlands are bloody expensive! The "NS" (National Dutch railway company) offers a shitload of options to get discounts; it is a mess and hard to find out which one is best (-> cheapest) for your typical commuting behaviour.
Script to pick the cheapest train subscription option for your travels depending on:
- Number of times a week you travel
- How many of your train fares are during peak or off-peak hours
Include a "I travel only in weekends" option and add the weekend subscription
