P&O Concessionary Units.Anyone used them or know about them?

[Wh00sher]

According to P&O T&C Concessionary unit holders can get a discount.

I believe you need to own 600 units, but whilst I have tried looking online, I can`t seem to find where you buy there or how much they are.

Has anyone had any experience with them ?

Apologies if this has been discussed before, I couldn`t find it.
