Re: I can choose the things I want.
Oh, but I do choose what I want at least from the fresh food section.
But I shop locally. I have two Butchers within walking distance. One makes the best sausages in the land (IMHO). The Farmers market and farm shops (for veg) supply the rest.
For the 'dry goods' then mostly I'll buy the own brand not the overpriced heavily advertised branded things.
However, as an old grumpy, I eschew anything that is advertised. Not that I see many anyway.
Each to their own.
