This kit is available on QVC.com - it costs $45 at the introductory price, including shipping, and contains Medieval, Saint Pink and a Butterfly Ball in Sigh, which is a QVC exclusive colour. Sigh is a sheer rose - picture below. I have and love both Medieval and Saint Pink, and I would dearly love to get my hands on that Butterfly Ball. The item number is A199188. Here's hoping that QVCUK can get hold of this line too.
