Get a radon test kit for your home for only $7.95 w/free shipping via the MN Dept of Health website (if you live in MN).
That’s 53% off & includes the lab test. This is a GREAT deal because most test kits in stores are more expensive and do not include test results.
I found out about this deal from our handyman at Mac & Hammer (check his ad on my site for a 10% discount on your first project!) If you don’t live in MN, check your state’s dept. of health website.
