Super Offpeak ticket availability

[Winthorpe]

I have a quick question about the availability of Super Offpeak tickets. Are Super Offpeak tickets sold with limited availability? In other words, can they sell out?

The reason for the question is I am considering travelling on the London Euston to Birmingham Stations £20 Super Offpeak. I am due to travel in a few weeks, but my plans are not yet finalised. Can I save buying this fare the day before for example? Or is there the possibility of a limited number running out?

Edit: removed link to wrong fare on Br Fares

No, you can buy this ticket at the station if you want, there is no quota.

Brilliant, thank you for the quick reply.
