As the clock struck midnight last night I had wondered what the fate of the NS Group ticket would be.
As it turns out, NS have extended purchases until 31st March 2014 and tickets must be used by 31st May 2014. There is the exception that it cannot be used on 26th April 2014, which is King's Day (a national holiday in The Netherlands).
Credit to them that they haven't raised the price of the ticket either, as they made a unilateral price hike on other tickets for the new year.
Updated terms and conditions (with the help of Google Translate) below, and tickets can be bought here:
