It saves food from spoiling. It is cost effective and I can’t even imagine all the dish washing it saves. An interesting use I have found for it was: I would wad it up and stick it in the gaps in my sleep apnea mask, preventing the air from whistling into and drying out my eyeball. I’m sure many people have many, many different uses for it. Feel free to share them and help us all be that much more thankful for Saran Wrap.
