I don't know about you but I love free samples. After entering your information, you will be asked if you want to wait for the free sample or you can print off a $1.00 coupon on the spot. I personally chose to wait for the sample and I can't wait to get it! I use Purex all the time and I am excited to see how well it work with the Zout. http://freesamplepurex.com/freesample/
