I guess that would be contingent on what you were storing. If you are storing expensive steaks and seafood in quantity, and you want it to be just as flavorful when you get around to eating it, I'd say yea. If on the otherhand you are storing boxed fish sticks (extreme example but you get the point) then I'd say bah. . . why bother. . . .
You also gotta make sure it is wrapped properly, etc. But that is a whole different post. . . .
