PENNY printed its frozen prices on the pack — a printed price can't be silently raised
the problem
Inflation made shoppers doubt PENNY's low prices hold — a promise 'prices won't rise' is easily broken, so not trusted
background
Across Europe's 2022-23 inflation surge, shoppers learnt to expect prices to keep climbing and had grown wary of low-price promises: a discounter claiming it would hold the line sounded cheap precisely because the claim cost it nothing to abandon. Existing brand advertising of the 'we are great value' sort is part of the problem, because saying it is what every rival then says too, and the promise lives in words that can be reversed at the next price review.
PENNY, the REWE Group's discount chain, wanted to rebuild credibility as a price-stable brand without that kind of hollow reassurance — and it had to do it across more than 2,150 stores where any packaging decision is a large operational commitment.
what everyone would do
The standard response to inflation-era price distrust is to advertise the message 'our prices won't rise': run low-price brand campaigns, tout locked-in prices in an annual-price promise, and generally repeat a claim in words. That approach fails precisely because it costs the chain nothing to abandon the promise later, and a customer primed to expect rising prices has no reason to treat a talk-track promise as anything but marketing.
what they saw
PENNY saw a discounter's price promise costs nothing to break, so shoppers never buy it. Printed on the pack, the price can't change without reprinting thousands of units — spend, not words, is what a shopper believes.
the move
PENNY printed the fixed retail price directly onto the packaging of a range of own-brand staples (bread, oats, salt, chips, mayo), with the line that printing the price is a way to make it stick: 'If you print it, you can't change it.' The pack itself became the promise, and a stripped-down out-of-home campaign in the same visual language reinforced it.
why it works
Because the price was printed directly onto tens of thousands of finished packs sitting in 2,150 stores, raising it stopped being a quiet spreadsheet decision and became a visible, expensive production change: to move the printed price the chain would have to scrap and reprint all those units, an operation on a scale any observant shopper, employee or reporter could notice. That structural cost is what separates the claim from the dozens of identical 'we won't raise prices' ads that cost nothing to walk back, so a customer comparing PENNY against rivals reads the packaging not as an assertion but as a locked-in fact. The mechanism converts the discounter's weakness — a cheap promise, cheap to break — into its strength: a promise made expensive to break, and therefore believable.
the payoff
Won the Cannes Lions 2025 Print & Publishing Grand Prix; per PENNY's own figures it sold 1.4 million items in four weeks — self-reported.
where it breaks
The move only bites where the printed asset genuinely constrains the backend — a pack that can be quietly relabelled at the factory in a day, or where the chain can simply add a thin sticker or shelf tag over the printed price, empties the mechanism of its cost. It depends on the printed price being economically the operative price for a long production batch, so products with fast price cycles, promotional skews, or frequent rebranding cannot carry a fixed print. And because inflation is the emotional driver, the mechanism is strongest in a moment when rising prices are the shared fear; in a deflation or stable-price environment the same pack does less work. The encouraging sales figures are PENNY's own reported numbers, not an independently audited result.
what came after
The campaign won the Print & Publishing Grand Prix at Cannes Lions 2025 and a Grand Clio for Creative Effectiveness, and is now cited in packaging and retail marketing writing as the model for turning a brand's price-stability claim into a physical, hard-to-reverse commitment rather than an ad assertion.
