This is almost one of those too good to be true situations. In short, in the UK, if you show a bite card at certain cafes you'll find at train stations, you can get 20% off. Log In It's free to sign up, and I've never had any spam from them. The only downside I can see is NOT having one. I think certain cafes charge more at train stations, in a similar way to how they do so at service stations, and this card just helps address that balance. (and exclude those companies that don't use it) As such, I don't go out of my way to use mine, but in those situations where I have to eat at a station, it's nice to know that for the effort of filling out a form, I'm saving 20% every time. And past midnight, you don't have many shopping options! Hope you all enjoy and get one soon, savetoday
