Travelling to Wales for this on Sat. Can you buy a ticket at the ground on the day?

Copied this from the club website. It's under 'Club Statement - Ticketing' dated 31st July.......

As a result tickets for the Crewe Alexandra game on the 11th August will be available for purchase from Wednesday 1 August: online via the Newport County AFC website and at the Newport County AFC Club Shop in the Kingsway Shopping Centre up until Friday 10 August; at Rodney Parade on Saturday 11 August from 10am.

Hope that helps.

Thanks
