Actually, on any given day some subcategories can be headed with single digit sales. Others might need thousands. Amazon slices and dices their categories to help buyers find books so there are lots of categories to slot books in.

This data set is a time slice snapshot.
Further slices will provide further snapshots to enable time-based analysis.
