There is no 'organization'. Sellers have repeatedly asked for a 'sold' column but have never been granted one as this would show to potential sellers how poor the sales are. They have promised a variations option to list as on eBay. This hasn't happened. The forum cheerleaders come onto the review sites and leave five stars - they were once asked to do this by management after a spate of poor reviews - yet they are complaining about the mess the categories are in.
Unless you are selling stamps or postcards, forget it. eBay may have the fees, but they also have the sales.
