Polly Arrowsmith is a savvy bargain shopper, and knows exactly when her three local supermarkets make their daily price markdowns.
She estimates that hunting out the yellow discount stickers saves her hundreds of pounds a year.
“There is no doubt I get a dopamine hit when I get a yellow label food item,” says London-based Ms Arrowsmith. “It is a small hit, but I do acknowledge the moment of joy.”
That daily ritual of pocketing a yellow sticker saving could soon be coming to an end. That’s because supermarkets are adopting dynamic pricing, controlled by artificial intelligence (AI) software.
It involves digital price tags that are displayed either on the shelf below the food items, or on high-tech stickers attached the product itself.
