You're right. That's what happens when you get liquid Christmas presents.
So a season ticket is actually the cheaper option - which makes sense because the club will want all that cash upfront.
But if you're going to be missing games over the summer due to commitments, holidays etc, the EZI ticket looks your best bet, especially as it's saving you £8 a game

Has anyone on here purchased one of these? I’ve bought one online but basically just got an e-ticket like when you purchase game day tickets. Does anyone know if you’ll be able to pre-order online and apply the discount or is it something you have to show on the gate each time?

Asked the club the same questio n.

Reply from club states that Ezi ticket needs to be produced when buying match ticket from club. Seems to suggest that there is no online.
