About ShrinkRadar

ShrinkRadar answers one question: did it shrink? We check a fixed list of everyday products daily. Net quantity comes from Open Food Facts / Open Products Facts; prices come from the crowdsourced Open Prices database (most recent US price). We only publish values we actually fetched — missing data is shown as missing, never estimated.

A finding is logged when a newer check shows a smaller net quantity in the same unit, or a higher price per 100 g/ml.

Known cases are historical before/after changes reported by news outlets, advocacy reports and reference works; each links to the source we checked.

Spotted a shrink? Corrections and tips are welcome.
