I’d be surprised if ‘shrinkflation’ isn’t word of the year for 2023. For those unaware, it’s the reason why prices for some products have stayed the same while their size decreases.

This article is about Carrefour, one of Team Belshaw’s favourite overseas supermarkets. They’ve added warnings on shelves to “shame” brands. The thing is, as this thread from Mario Zechner shows, it’s not as if supermarkets aren’t in the price fixing game. Also, as I wrote about recently, stores are essentially panopticons.

While I’m on the subject, you might be interested in this crowdsourced website which tracks the differences in size of packs of everything from toothpaste to shortbread biscuits.

The French supermarket chain Carrefour has put labels on its shelves this week warning shoppers of “shrinkflation”, the phenomenon where manufacturers reduce pack sizes rather than increase prices.

It has slapped price warnings on products from Lindt chocolates to Lipton iced tea to pressure top consumer goods suppliers Nestlé, PepsiCo and Unilever to tackle the issue in advance of much-anticipated contract talks.


Carrefour has marked 26 products in its stores in France with the labels, which say: “This product has seen its volume or weight fall and the effective price from the supplier rise.”

For example, Carrefour said a bottle of sugar-free peach-flavoured Lipton iced tea, produced by PepsiCo, shrank to 1.25 litres (0.33 gallon) from 1.5 litres, resulting in a 40% effective increase in the price a litre.
