In an age where pens are being replaced by pixels, there are some who still prefer the old ways.
Muriel, from Tonypandy, is one of them. She's 77 and has no internet, no online banking, no click and collect and no price comparison sites. And that's costing her. It means no online discounts and no online-only offers. And despite its age, the well-established telephone is actually becoming more expensive.
Muriel admits the internet has a part to play in modern life and she has used it, but there are still seven million people in the UK who haven't. And three quarters of those are among the poorest 10% of society.
And for those people, it means an online world remains inaccessible.
As for businesses going paperless, some argue their green motives are actually driven by profit margin.
With so many of us now spending upwards of eight hours a day communicating online - for people like Muriel, a simple letter will do.
