This question comes from someone in a Facebook group and they want to know if it is possible to list your item in more than one category? They go on to say when your product fits more than one category, how do you get it to show in the other category besides the main one ? Well Amazon does not give you any way to add a second category. Amazon itself will at their discretion add your item to another category and also there appears to be some automated process that sometimes adds your item to multiple categories when it is applicable.
