Package-size history builds week by week — changes appear as weeks accumulate.

Methodology

We read every flyer line since April 2025 (over 2 million). A product appears here only if a single-product ad prints its size, each size was advertised for at least two weeks, the new size is 5 to 35% smaller, and the old size never appears again in any flyer afterwards — combined ads and "650–750 g" ranges included. A cut of more than 35% is almost always a different format that already existed. Every change is checked by hand against the flyers before it is published; sizes come from what the flyers print, never guessed.
