THE REFERENCE SHELF
Price & counts
Rolls, bags and cases: multiply the right numbers
Count the actual consumable pieces rather than the packaging layers.
Compare pad prices per actual pad
Use one obtainable price and the exact selected quantity before comparing packs.
Bulk pricing needs a delivered-cost comparison
More pieces can lower a ratio while increasing the amount you pay today.
Reusable and disposable need different cost records
An honest comparison keeps unknown lifetimes and care costs visible.
A dated US price check: three distinct formats
Use the observed amount as a starting point, then verify the selected checkout.
