Shrinkflation Supermarket: a free game about unit prices
The bag stays the same, the crisps inside disappear, the price goes up. Find the real best buy.
What is Shrinkflation Supermarket?
Same bag, fewer crisps, higher price. Each aisle shows three packs of the same thing: a “new look” pack, a “family size” and the plain one. Pick the best value by its price per 100 g or 100 ml.
Shrinkflation Supermarket is a free satire game about shrinking packs. The bag looks the same; the grams inside quietly drop.
Each aisle shows three packs of the same thing, often with a “new look” or “family size” label. Pick the best value by its price per 100 g or 100 ml.
