One Tesco shopper has shared a warning to others who are trying to save money by checking product labels in supermarkets.
The Extreme Couponing and Bargains Facebook group member shared the warning post earlier this week.
They told the group that they, like many others, spend a lot of time looking at the cost per 100 grams section on supermarket price labels to see if they are getting the best price.
However, during a recent trip to their local Tesco, they saw that a label for Kenco Smooth Instant Coffee granules was "not accurate"
The coffee product was priced at £6.70 and weighed 200grams.
This meant the price per 100 grams should have been £3.35 but it wasn't.
The label was printed showing the price per 100 grams as being £2.23 - which would've been correct if the Kenco product was a 300 gram jar.
The post read: "If you're like me you'll spend a lot of time looking at the cost/100g section on supermarket shelf labels. Just a warning to double check, as sometimes they're not accurate!
"The price per 100g of this coffee should be £3.35, but it's only showing as £2.23 - the label has been printed as though it's a 300g jar.
"Ended up getting a jar of Nescafe original as it was only £2/100g with a Clubcard."
The warning post garnered over 150 likes and over 100 comments and many shared frustration at these mistakes and thanked the poster for the warning.
One Facebook user commented: "Oh wow, I always check that. Thanks for the heads up" whilst another added: "I always trust those labels too!".
Another said: "I noticed this last week in Tesco too. It was so obviously wrong when they labelled 500ml olive oil at £5 as 88p per 100ml when it should have been £1/100ml!"
Another said they had in fact raised this issue with the supermarket chain a few years ago.
They commented: "I raised an issue with Tesco a few years back, when I spotted a number of incorrect 'per 100g' type figures on the website.
"Their response was that 'these are only a guide', with a suggestion that people should be doing their own calculations
"I thought about trying to report it to Trading Standards or whoever's responsible for Weights & Measures, but was busy with other things and never got around to it."
Other Facebook users noted that the issue could "technically" be "false advertising" with others claimed to have spotted similar mistakes in other supermarket chains.
One commented: "I thought that it was totally illegal to have misleading information. Surely it's a form of fraud?"
Another added: "Can they legally do that??? Where's the point in having the weight breakdown if they can just put whatever they like??"
Tesco told the Mirror that the image was "old" and that it was not the current label for this product.
The supermarket chain also said that it has "taken steps" to ensure the labels in its stores for the coffee product are correct.
A spokesperson for Tesco said: “We are sorry to hear about this.
“We go to great efforts to ensure that the correct pricing information is displayed on our shelf edge labels and so errors are extremely rare. We are investigating what happened here.”
