Supermarkets normally have a single price for each type of produce. What if people could choose cheaper options of the same produce because it is less fresh or looks less than premium (some blemishes, scratches, etc.).
"...U.S. supermarkets generally reject produce that doesn't meet their standards for appearance or earn top U.S. Department of Agriculture grades, leading to waste. The U.S. trashes about a third of its food supply, according to USDA estimates. The National Resources Defense Council (NRDC), an environmental action group, calculates food waste at 40%..." Source
Supermarkets could have a discount produce section where less pretty, slightly damaged or very ripe items could be sold at a discount price. The produce could be pre-bagged, and/or pre-cut to make it more convenient for the consumer. It might be an economically attractive offer for:
1. Budget conscious people
2. People that might need the produce to make something that doesn't depend on the appearance of the food
3. People that are looking for something that could be eaten right away so they are not concerned with shelf life
The supermarket could squeeze more out of their fresh produce instead of throwing it out and people might save some cash given additional options. If it works, we would also start changing perceptions on what is OK just based on its looks.
