Floss and Wipe Free Samples

This site's sample link keeps sending me back to the home page, either there
are no samples left or the link just doesn't work to start with

I'm not sure how to get the sample. When clicking on the sample link (found on thehome page) it brought me to the page shown here, but it was a money back guarantee, implying that you would have to buy their product in order to try it.
