See this? This is the "discounted produce cart" at the Hingham Stop & Shop. Sometimes, you can find really good deals there. Don't have shame people! Have pride! The best "find" I think is bananas - if you are going to make bread or if you are like me, I just peel them and freeze them individually for smoothies.
If you are going to cook tomatoes, you can also check this rack. If you want to make zucchini bread, check this rack.
Would I buy everything off this rack? Nope. But you're not going to die if you find something good on here.
