This is the best summary I could come up with:

French supermarket Carrefour has put stickers on its shelves this week warning shoppers of "shrinkflation" - where packet contents are getting smaller while prices are not.

"Obviously, the aim in stigmatising these products is to be able to tell manufacturers to rethink their pricing policy," said Stefen Bompais, director of client communications at Carrefour.

Carrefour has identified 26 products that have shrunk, without a price reduction to match, made by food giants including Nestle, PepsiCo and Unilever.

In June French Finance Minister Bruno Le Maire summoned 75 retailers and consumer groups to a meeting about prices, and has accused manufacturers of not toeing the line on inflation.

British consumer groups have also warned of "shrinkflation" affecting the value of common items from cat food to chocolate biscuits.

Supermarkets use the same "shrinkflation" tactic with their own-label products, he added, aiming to keep to a certain price point, for example £1, by introducing cheaper ingredients, or making portions smaller to manage rising costs.
