Pleased to see I’m far from alone in trying to avoid American products (This un-American life: can you really divest yourself of everything from the US?, 19 April). Mostly there are alternatives. There is no need to make your own cleaning products – for example, there are Bio-D and Faith in Nature. I have a Kobo e-reader and a Doro phone. A good source of alternatives is Ethical Consumer magazine.

At last, a great use for robots – running half-marathons so I don’t have to (Humanoid workers and surveillance buggies: ‘embodied AI’ is reshaping daily life in China, 21 April).

Terry Bates in London writes that his newspaper costs less than a cup of coffee (Letters, 20 April), and Pete Bibby in Sheffield that his costs less than a pint (22 April). I can buy a pint of bitter in my local pub for £1.79, or a coffee for £1.71. My paper of choice costs me more than either.

On the rise of extra time in school exams (Report, 23 April), as a teacher I’ve always wonder what provision employers make for employees who used to get extra time.
