I think you’ll find Hora that by buying quality, you don’t need as much.
Most people that shop at supermarkets make the trip once a week, bulk buying, some/a lot of this gets thrown away, along with all the excess packaging.
I care where my food comes from, how fresh it is, and believe me the trash that some supermarkets try and sell you in the fruit and veg section should have a health warning on it.
And when our town was faced with the threat of building a supermarket, the roads were closed, telly news came to film because most of our town came out to demonstrate against the idea.
I’m not totally against supermarkets, Booths and even the Co-op do try and source their goods locally where ever possible.
