IDK, I mean I kindly see your point, but at the same time, how does one find out about a new distributor they've never used before or never been cold called on. What are the odds the guys at GSG are going to tell me to call Athens Paper for the cheapest cost per roll. What are the odds your salesman will be honest about how the roll is $25 cheaper per roll, but the material won't blockout anything behind it. It's definitely not the most exciting post on the forum at the moment, but isn't it what the forum is kindly built for?
I myself hate cheap materials, and would decline a large order if I was not comfortable with the materials being used. Also, I'd rather work with materials that I enjoy cutting/printing/engraving on and selling for a modest profit, as opposed to selling materials that make me want to jump off a bridge for a better profit margin, but that's just me.
