John Walsh: Not sure I fancy a pork chop from Amazon

The coming war between Amazon and Britain's superstores to seize a chunk of the UK's online groceries-delivery market promises to be titanic. The chore of buying the same old fruit-'n'-veg-'n'-chicken-thighs-'n'-bread-'n'-wine every week has become so boring that lots of us have turned to using Tesco's or Sainsbury's', or in my case Waitrose/Ocado's, computerised shopping services. Not all of us, of course – just 13 per cent of food shoppers, apparently – but it's a figure set to rise.
