As today's high inflation pushes Americans to reconsider how, when and where they shop, salvage food stores are gaining traction. Nicholas Duke, manager of Uplifting Deals in Asheville, N.C., joined "Fox & Friends" on Monday to explain how salvage food stores buy overstock from traditional retailers to then resell in their own stores. Duke said the existence of "best-by" or "sell-by" dates on items indicates to retailers when to freshen their food stock. The products, though, are still salvageable.
