Cardiff Park & Ridde

I have tried to book Saimsburys park & ride and get the following message:

Sorry, you cannot buy any more "Number of Car Parking Spaces" tickets to event Pre-Booked Park & Ride v Cardiff City 24/01/2017 18:00.
Sales of "Number of Car Parking Spaces" tickets to this product type are limited to 0 tickets per event per history per person.

Are spaces sold out or is it a website problem?

Sounds as if car spaces are sold out but bus places are not ?

It may be a website glitch, worth trying again later.
