Counted unitsItems, sheets, pods, or pieces
Use whatever count best reflects how the product is consumed.
Comparable qualityNot all items match
Paper towel sheets, trash bags, diapers, and pods can differ in size or strength.
Bulk storageSpace still matters
A lower item price may not be worth it if the pack is hard to store or unlikely to be used.
