Because I buy them in bulk, I never reuse any of the bags. Aside from the savings on food, there is also the savings on time and effort. My main use for the Food Saver is for meat. I would rather wrap six individual chicken legs and thaw out two at a time using the small pint bag. I have better control over how much food I thaw out and cook. Never more than I am going to eat. Then toss the bag. Not worth the effort to wash, dry and save.
