Young Person's Railcard Oyster Discount

This should probably be my facebook status or something, rather than an entire blog post, but I was astounded to discover this week that it is possible to get a discount on (at least.. I haven't bothered to look up the details) off-peak day travelcards on Oyster with a young person's railcard. I have so far saved about £3 since I found this out less than three days ago. Ok, so it's not a massive amount of money, but it's certainly non-trivial. In order to get this discount, all you do is go into the ticket office of any Tube station with both cards, and they'll do it for you (the Oyster card has to be registered, but that's probably a good thing to do anyway).

Anyway, the reason I'm writing this as a blog post is because it made me think: what the Hell is the student union doing? Does everyone else in the world already know this, in which case how come I'm the last to find out? If not, why on Earth is QMSU (and the NUS, for that matter) not shouting it from the rooftops? This could be saving a lot of students fairly significant sums of money, and most of them (ok... some unacceptably high percentage of them) have no idea about it. Seriously, this is probably the one useful thing the student union could have done for me in my time at QMUL (apart from my Topshop discount...), and they haven't. What are these people there for?
