Let's take bananas for example. When they're fresh in the store they have a greenish color (not ripe) and you pay full price. Once they turn yellow or get those black spots (ripe), the price drops. Most people avoid buying bananas with spots since they consider them rotten. And they're wrong! The part you eat is quite good and has nothing to do with the exterior. What about you, do you avoid buying cheap, overripe fruit?
