WonderLister is the world’s best eBay listing management software for many reasons, one of them being how easy it makes your day-to-day operations by letting you organize your data the way you want. WonderLister allows you to create your own folders and sub folders within a folder to any depth. Folders are of two types based on how you wish to use them. User managed folders are those in which you manually add or remove your items (listings or sales). Rule based folders are those for which you can set a predefined set of conditions. All items (listings or sales) that satisfy the set of conditions, will automatically move into the specified folder.
