Sometimes the greens in grocery stores are wilted. As long as the leaves aren't yellow or brown, they are still salvageable. All they need is a drink of water. Trim the stems and place them in water. Set the timer for about an hour. Check and add more time if still wilted. It's important to remove them from water once revived. If they sit in water for too long, they will turn yellow and possibly wilt, again.
Then wrap the leaves in a thin kitchen towel or paper towel and wrap again in a plastic bag or container.
