WonderLister is the most advanced and powerful eBay bulk editing tool. If you have been selling on eBay for some time, you may know that you would need to edit many of your listings with similar types of changes. You may just want to change store categories across many of your listings or decrease the price by say, 10% on multiple listings. Bulk edit would let you do this very easily. In addition, you can search in text fields like title, description, condition, custom fields etc. and only if search is successful then carry out the specified edits. Just imagine, if you were to search in your tens of thousands of listings for a specific term and if found, replace it with another term!
