Against official inflation: BLS CPI-U (US) “other food at home” changed +1.8% (12 months to Sep 2026, a broad match for this category). The size cut alone raises the price per ounce by +6.7% if the shelf price stayed the same (the source recorded no prices). Every case is compared the same way in the ShrinkRadar Index.
