I went to a cooking class a while ago and learned an awesome little trick on how to keep your lettuce fresh longer. What's the trick? Paper towels! That's right! You just need to put a folded up paper towel in your bag of lettuce. Now, in the previous post, one of the foods to never buy again was bagged lettuce since it's much cheaper to buy a head of lettuce. So if you buy a head of lettuce, you want to wrap the lettuce with a paper towel to remove all of the water they spray on it at the store. Once you have removed the excess water, get a new paper towel, wrap it around the lettuce and put it back in the produce bag. This will seriously lengthen the lifespan of your lettuce. Other things you can do are: keep it cool and give it room to breathe (store it in the produce drawer with lots of room so the leaves don't get bruised).
