Detect shrinkflation by comparing size and price per unit between old and new.
Comparing the amount and the unit price between an old and a new package reveals whether you are paying more per unit, which is shrinkflation. Packages that get smaller while the price stays the same are effectively a price rise, and only unit price exposes it.
