Hello, I own a small grocery store and some of the items that I buy I buy from multiple vendors and/or at different prices or, the price will change that a vendor charges. How do I handle this ? I tried to enter the same UPC as a new item at a new cost but I was unable to save it. The screen prompted "This item already exists" and that prevented me from saving it. I've yet to, purchase Iventoria, I'm trying out the trialware. Thanks.
