If you are fed up reading all this advice, why read it?
No general advice on ways to reduce your food bills applies to everyone, or indeed anyone. These are, as they say on the packaging around food 'servingsuggestions' . Some people will find some of them helpful, some will find none of them helpful. iN ewhich case why waste time reading them.
It is the same with suggestions about how to reduce your heating bills, or spend less on clothes, or get fitter, or thinner. There are always people around prepared to offer generic advice to all and sundry. And there will always be people reading them to whom they are irrelevant.
The simplest solution to most people's outrage at these articles is not to read them, then they will not outrage you. Use your time doing something more pleasurable from stroking a pet, to reading a book or enjoying a glass of wine.
