Here is a link to a video demonstration of the Big Shot.
*Note this is the Pink and Black version HOWEVER the SU version and Teal and Black version ARE THE SAME MACHINE. The only differences are the color.
Stampin' Up has partnered with Sizzix to sell the Big Shot and Exclusive Dies. The Big Shot IS NOT EXCLUSIVE to Stampin Up. Only certain Dies.
