If I’m going to skin or peel the vegetable, I go with the cheap stuff. If I’m eating the skin then I go organic. I never buy the prewashed lettuce and salads when they are on sale because those have already started to go bad usually. And when it comes to things like berries, strawberries, tomatoes, and peppers I go with whatever looks like it will taste the best. Cheap blueberries for instance, absolutely do not hold up against the good stuff; life is too short for tart blueberries.
Value was making value as you put it, long before rapid trading. Speculation and arbitrage are like the first two things that develop in any economy. Any entrepreneurial grade school child trading candy, baseball cards, pogs, hotwheels, or whatever the hot new thing is has probably seen both first hand.
