In light of the Birmingham PlusBus recent 75% price hike, I was wondering if of the railcard I have or might get next would qualify for the discount. The Birmingham PlusBus page - https://www.plusbus.info/birmingham - lists the normal (£9.00) and railcard discounted (£5.95) prices but not the valid railcards.
If you head to the main PlusBus page on railcards - https://www.plusbus.info/discounts - it lists quite a few. Some have restrictions called out, eg the Two Together Railcard requiring you to buy 2 tickets together. It includes the normally South-East only Network Railcard in the list, without any mention of limitations:

I can't seem to get any sites to actually sell me a Birmingham PlusBus with a Network Railcard discount, which is what you might expect, but isn't actually what the PlusBus site seems to claim... The list of railcards also doesn't mention any local or regional ones, which I'd have expected might quality in their areas?
So, that leads me to ask here - what is the actual list of railcards that are valid for the discounted PlusBus rate for Birmingham?
