I want to put up a stand at a local festival with many items that are current and some discontinued pc items. I was told by another PC consultant that we were not allowed to sell products we had on hand due to the warranties. I'd also like to show and sell some of the spices. Do I need to be concerned about the warranty on these items. I have many products that have never been used, and are still in the box, but the warranty would be in my name and from several months ago. How does that work?
