Lately I've been leaving mine at the store until I specifically need some
I haven't had a banana in the house in probably a month. I noticed that too many were getting tossed to the chickens (without the peel of course). I'll abstain and then when I purchase a small bunch I'll be sure to use them up for the things I like; on cereal, making ice cream or banana bread.
I've found out that if I am buying food that is going bad, then I am buying out of habit. Not a good thing.
