Price per sheet is the most useful number in this category and the easiest to get wrong. Two records from the US panel show why, and both are ordinary retail behaviour rather than anything suspicious.

The 300 count with an unknown base pack

Winner Medical sells an 'Upgraded Thicker' 100% USA cotton wipe as a 300-count offer at 23.99 USD. That works out to about 0.08 USD per sheet if you divide by 300. But 300 is the total in the offer, and the page does not establish how many physical packs that total is made of. If it is six packs of fifty, the base pack is 50. If it is one large pack, the base pack is 300, and the shelf and carton implications are completely different.

For a consumer, none of this matters. For a buyer building a comparison, it matters twice: the per-sheet figure is still roughly right, but the pack format and the freight profile are unknown, and those two drive the landed cost.

The zero that means unavailable

POND'S US listing for its Ultra Soft Dry Face Towels, 50 count, carries structured data that says the item is out of stock with a price of 0.0. A script that reads price fields and divides by sheet count would record a free towel, or crash. Neither is a data problem you can fix later; it is a data problem that quietly enters the average.

We excluded that record from the price calculation and kept it in the database with a note. The same rule applies anywhere a price is captured: zero is a missing value or a placeholder, not a price.

Two denominators, two questions

A one-pack price answers 'what does this cost on the shelf'. A price per sheet answers 'what does coverage cost'. Only 84 records in the panel had both a positive listed price and a verified total sheet count, which is why the two metrics have different sample sizes in every market. Germany had 11 one-pack prices and 14 unit prices. Korea had one one-pack price and twelve unit prices. Those gaps are not errors; they are what the pages allowed.

What this does not say

We are not suggesting the 300-count offer is packaged any particular way, and we are not claiming that zero-priced towels are free or that the listing is misleading. Both are ordinary page structures that a price comparison has to handle explicitly. And a price per sheet says nothing about quality, fiber, or whether the towel suits a given use.
