Do you use a lot of bananas in your smoothies or other recipes? Make sure to check your local co-op for discounted bananas and stock up! I buy several bunches of discounted organic fair trade bananas for .49-.79c/lb. whenever I can. Just because the skin has black spots does not mean the banana inside is no good. Just peel them, then layer them in zippered freezer bag and freeze. Don't stack them on each other inside the bag or they are harder to separate. I try to put them in whole and not in chunks for the same reason.
