Superstore Theme Mystery

http://www.remotestylist.com – i can’t figure out for the life of me where this line of code is coming from. It’s not in the main content and its not in the theme. I upgraded yesterday to woothemes superstore 1.0.8 and this grey box showed between the slider images and the get now line … anyone? how do i delete it
