I have been buying Pampered chef for about 4 years now and love it! During that time, I have lots of items in my collection. I am now thinking of becoming a consultant. My question is, since I have almost every item in the Super Starter Kit, am I obligated to purchase it, or do I have any other options? Will P.C. allow me to make substitutions? I have everything in the kit except for the apron and a few other gadgets. Thanks!!
