That is a feebay thing; a book on china goes in china, a jewelry holder goes in jewelry. Guess mustard gets listed with spoons?
Usually I like being able to list in two categories. i.e. vintage tablecloths, Antiques, and in Home and Garden. Logically, people look in one or the other.
But pull out craft books and put in crafts? Or make a duplicate category in Crafts so it is in both? Those who only look in one place will assume ebid has less craft books.
And why have a category/sub category way of searching if stuff is divided and put in a couple of completely different places? A universal search has to be done to catch all items.
Please no more sub categories! OK with 100,000 items, but not with just a sprinkle in each subcat because it is neat. Waste of keystrokes (we ain't getting any younger), and it discourages window shopping. Sometimes a buyer does not know they need it until they see it. They will never see it is it is tucked away with its five other little buddies in some sub cat.
