Say you were travelling from Brussels to Amsterdam by train, spending 2-4 days in Amsterdam using public transport then travelling from Amsterdam to Antwerp by train.
According to the NS website, it seems you can get a NS Flex dal voordeel card for €5.10/month which offers substantial 40% discounts on train travel.
Is there any way for non-residents to buy this in advance or online so that it can be used for all train tickets between Belgium and Amsterdam?
If you can't buy it until you get into the Netherlands, it seems it would still be better value just to use it for the return journey - where can it be acquired in Amsterdam?
It seems last-minute tickets are ridiculously expensive. €50 on IC and €86 on Thalys. Is there really no way to get a discount on these coming from outside the Netherlands. For multiple people, 40% discount would be a huge difference.
