Flex I buy is now available on every item. And yes they are mentioning the fees. And there’s also a box on the right hand side of the screen with it. I don’t think they explain what the fees are but it’s in the Ts&Cs.
I think it's important (considering there weren't fees before) and how casually and regularly presenters offer up flexi as an option, to clarify exactly what the end cost is. because it makes sense that a bargain becomes less so with hidden charges
