Who knew? (Yes, I’m being ironic)
I’m not sure what that person meant by “local markets”, but supermarket competitors are no cheaper for the people at the bottom buying the cheapest stuff (who are the ones actually at risk). Maybe in the middle and upper tier products you might start to see a difference but for homebrand/off-brand items Colesworth is as good as it gets.
If they meant wholesale/farmer’s markets then I would definitely agree that you can save tons of money. Fruit and vegetables are the absolute worst, I would never buy those at Colesworth unless I was desperate. They are ridiculously expensive and often poor quality.
