A mum has revealed the startling price difference after carrying out the same Tesco food shop in one of its rivals.
Shopper Claudia carried out her usual food shop in Marks & Spencer only to be billed a fraction of the cost, despite its reputation as one of the most costly supermarkets.
The M&S bill came to almost £57, while she claims her Tesco shop of the same items reached £91 the week before.
The mum took to TikTok to share her thoughts, claiming she had always previously been a "Tesco girl".
"I just did something that I would never usually do," she began.
"My For You Page has been absolutely flooded with people doing comparisons on their weekly shops at places like Waitrose vs Aldi, M&S vs Tesco, and so on.
"So today, I thought, do you know what, I’m going to do my weekly shop at M&S and see if there’s that much of a difference.
"Now I am a Tesco girl and I will die on that hill.
"I just did the bulk of my shop - bearing in mind that we are vegan - at M&S."
Claudia added there were a few vegan alternatives she couldn't source from M&S, such as dairy-free cream and the vegan pizza base she normally opts for, claiming she would instead pick those up from Tesco.
"My weekly shop at Tesco last week was £91," she said.
"My total for today at M&S - £56.99. What?
"I’m just going to come and do my shop at M&S!"
She added that even after getting the extra bits from Tesco, on which she spent £25, the total came to £81.99 - saving her almost £10 on her weekly shop.
And, as an added bonus, Claudia pointed out that the "quality at M&S is unreal".
"I am now an M&S girlie," she wrote over her video, before adding in the caption: "M&S you’ve just gained a loyal customer."
"I used to work at M&S for 7 years and It is honestly the best food & they always try and keep the prices down!" one person commented on her video.
As another added: "Honestly I shop there quite often there’s so much that’s affordable fresher and fruit and veg lasts longer also I find!"
"It’s so true!" Claudia replied.
"I couldn’t get over the size of the peppers!""I spent £70 at m&s and got most of my monthly shop last week," someone else wrote.
"Lasts longer and fresher and better quality."
