How much do you save with Railcard on Oyster?

Okay, so, Railcards on Oyster... how much do you actually save? Well, let me tell you, it's a game-changer. Seriously. I'm clinging onto my 16-25 Railcard for dear life (26 is looming, and I'm not ready!). That sweet, sweet one-third off off-peak travel? Gold dust, I tell ya. I mean, think about it – I'm always crisscrossing London, mostly off-peak anyway because who enjoys being squished like a sardine during rush hour? And that discount? It really, truly makes a difference. Like, last week, I went to see that new exhibition at the Tate Modern (amazing, by the way), and I swear I saved at least a couple of quid just on the tube fare there and back. It all adds up, doesn't it? Especially these days. Rent is insane, avocados are practically a luxury item... So yeah, a little saving here and there? Don't mind if I do! It makes London feel just a tiny bit less like it's actively trying to bankrupt me. Honestly, if you're eligible for a Railcard and you use Oyster, just get it. Don't even think twice. It's a no-brainer, right? Like, why wouldn't you?
