Hello. I am not very computer literate so do excuse my ignorance - however why am I having problems trying to make different sub-categories in my book store. All I want to do is sell books, some of my books are general novels so am happy with the 'fiction' category, however some of my books are rare and collectible and not all pre 1950. Am becoming very confused with the parent category. And what category do I list collectible post 1950's children's books in. I have some rare books, signed books, collectible children's books, collectible travel books etc. Is there a teaching facility somewhere on ebid that will give me information as to how to use categories for all of my books so that potential buyers can find what they are looking for? Babs.
