The operator’s read

Caution

The larger pack only wins if you use it all. For perishables, waste erases per-unit savings fast — a 20% cheaper pack you throw 30% of away is a loss.

Methodology

Unit price = price ÷ quantity, compared directly. The saving percentage is measured against the more expensive option.

The perishability caveat is the classic bulk-buying trap: per-unit price is only realized on units actually consumed.
