Because I live alone, it's less expensive to buy a whole head of lettuce or leafy green vegetable than in a plastic bag all by itself. When I get the head of lettuce home, I cut the core end off and remove any leaves that are bad. I wring a small terry cloth towel out with cold water and wrap the head of lettuce in it. I then put the head of lettuce with the towel in a plastic shopping bag, press out the excess air, twist the top of the bag and fasten with a clothes pin or twistie. I put this in the refrigerator.
About every second day, I unwrap the lettuce and cut off any brown that may have appeared. I have kept lettuce for up to three weeks that are fresh and good. When you remove leaves, do not cut off with a knife. Just pull off or cut off with kitchen shears.

My tip is a way to save money and food with lettuce. I am a senior who lives alone. I buy the bagged lettuce because it is hard for me to cut up lettuce.
