Yes get a rail card! (you can order one online and it takes a couple of days to arrive or go into your local train station and buy one instantly there. Although if you buy one at the station you'll need all the documents and passport photo then, and you get given a paper railcard in a wallet. If you buy it online you just get a plastic card!) it's £28 for a year or £65 for 3 years.
Then take the rail card down to a tube station when you buy (and topup) your oyster an get someone to attach the discount!
Also not sure if your home is far from London (if you use long distance trains) some companies like Cross Country will give you an extra discount on top of the railcard discount - when you use your NUS card!
