i would suggest freecycle, then local home depot/lowes.
if you are in an area that usually builds for hurricanes, then yard sales.
Hi Lala! There are options online, or your local hardware store. Home Depot, Lowes etc. should carry them if you are in a hurricane area!
Lala: this may be a good place to start
Hi Lala. I'm Cindy. You can purchase hurricane shutters at Home Depot in their Doors and Windows Department. Best wishes Lala.
