The video description says "On March 21st, "The Difference is Clear". Check back then for the full short film." That description needs an update AND they could add a link inside the video to to to the full short film.
At the end of the video they do have an embedded link that says, "Click here for savings on non-drowsy Claritin."
That link goes to a coupon printing page where you need to install coupon printing software. I don't like doing it, but I did. I then clicked the Print Coupons button. No coupons printed right away.
A while later I tried again and they printed.
