Useless trade magazine - these are crappy trade publications that sell a bunch of advertising, contain no real information in them and are sent to your company for free but a call center pesters you every couple of months to confirm your information to "continue your free subscription" - we receive multiple copies of a dozen or so of these every month, such as Food Packaging News, Plant Manager Monthly, Food & Dairy Producers, etc., and they all go straight in the trash because they are useless wastes of good trees and I'm no tree-hugging environmental terrorist!  Then you get the added bonus of these call centers wasting your time on top of filling your recycling bin!
