The major change comes as part of a move towards using artificial intelligence (AI) in grocery stores in an attempt to kerb food wastage.
It could see automatic pricing on fresh products which would usually have a reduced sticker slapped on them as they near their use-by date.
Instead of a supermarket staffer walking around and labelling the goods, their prices would automatically change on the digital tag.
The snappy price shift would mean shoppers would see the reduced price sooner, and, in theory, nab the cheaper food quicker.
It’s already been trialled in supermarkets across the country, and is looking to be rolled out for further testing.
Experts say move should come as a relief to shoppers’ wallets, as well as boost supermarkets’ profits by reducing food waste.
Retail expert Clare Bailey told the Telegraph: “It is something that [retailers] should be looking to do much sooner rather than later, because the technology has been proven.
“I think as long as it is used for the benefit of the customer, or where a genuine price increase has to be made, then that’s pretty good use for the technology.”
However, until then, an expert recently revealed when each grocery giant usually reduces food prices throughout the day, so Brits can get the best bang for their buck.
Best times to get deals
Richard Price, director at online supermarket Britsuperstore, recently told The Sun when bargain hunters should be heading shopping.
He said the key was keeping an eye out for the yellow labels to products nearly at their sell-by date – while they’re still around.
The expert shared when shoppers should make their way into Aldi, Lidl, Morrisons, Co-op, Tesco, Sainsbury’s, Asda, M&S and Waitrose for deals.
Speaking about Aldi, Richard said the best time to visit for reduced products is before 8am and as the store is gearing up to close.
He added: “Fresh products with reduced prices will be marked by a red sticker, and are typically reduced as they are at the end of their shelf life.
“They will normally be discounted by either 30% or 75%.
“Dried groceries and tinned food may also be discounted if they have imperfections.”
Richard said the best time to venture into Lidl for reduced bargains is early morning and toward the end of the day.
At Morrisons, fans will want to rush out to their nearest store from 3pm to 5pm and then 8pm to snap up reduced items.
It was a different story at Co-op, Richard said.
The chains only slashes prices once throughout the day – 6pm to 8pm.
The expert said Tesco slashes its prices three times a day – 9am to 10am, 4pm to 5pm and the final round at 7pm.
Sainsbury’s usually slaps yellow stickers on products around 5pm, ideal if you’re heading in just after work.
But this can vary dramatically branch to branch, Richard said.
Asda puts yellow stickers on products early in the morning and towards the end of the day at around 7pm.
M&S generally reduces prices on its products once in the morning and twice in the afternoon, at 9am and between 2pm and 4pm, Richard said.
Waitrose staff apply yellow stickers to products two hours before closing.
