Several times a year, eBay refines the structure of selected categories in order to bring a more intuitive buying, selling and search experience.
The next round of category changes will take place the week of September 22, corresponding with Fall Seller Update. These changes will affect ePN partners if you are using Category IDs in custom banners, RSS feeds, link generators or any other widget that contains Category IDs as an option.
The updates will affect some subcategories within Business & Industrial, Crafts, Health & Beauty, Home & Garden, Motors, Musical Instruments & Gear, Sporting Goods and Toys & Hobbies.
For the complete list of changes, please visit this page and click through to the categories relevant to your website for more details: http://pages.ebay.com/sellerinformation/news/categorychanges.html.
