A mother complained about the cost of groceries at Coles after comparing her shop to Aldi... but not everybody is on her side after noticing a small detail

A mother has divided Aussies after complaining about the cost of groceries at Coles and comparing them to Aldi.

Melbourne mum Alondra Gataé vented her frustration on TikTok revealing she had spent $72 on eight items at Coles.

In her video, Ms Gataé claimed for $100 more she bought a full trolley worth of groceries at Aldi.

Ms Gataé showed the eight items she bought at Coles, then the trolley filled with her Aldi purchases.

The Coles items included deodorant, protein pizza slices, frozen dessert sticks, cottage cheese, a shower glove, an avocado and two cartons of free-range eggs.

Ms Gataé showed both receipts comparing the massive difference.

'Somebody make it make sense,' she said.

'Make it make sense how an extra hundred dollars, give or take, is the equivalent of a full trolley worth of food for two weeks from Aldi. Coles you suck.'

Social media users were mixed with some criticising Ms Gataé saying it was an unfair comparison as she bought brands at Coles that were normally more expensive.

'If you are trying to save money why did you spend $25 on two cartons of eggs?' one replied.

Another agreed: 'You can't compare when you buy the super expensive eggs over the home branded eggs. 

'Even Aldi sells organic eggs. Go buy the no name eggs and compare.'

'What bs look at the items you brought at Coles … now go buy those items else where the cost will be the same… stop lying,' another wrote.

'Buy the SAME items at each store, or it isn't a true comparison,' a fourth wrote.

Others were quick to sympathise with Ms Gataé.

'Coles and Woolies are an absolute criminal thieves…saying that Aldi are not as cheap as they once were…im missing Aldi in Tasmania terribly,' one wrote.

'Everyone should stop shopping at Woolworths and Coles for 1 months,' wrote another.

One added: 'Plain and simple don’t shop there.' 

Ms Gataé described some of the replies 'bloody crazy' in response to the criticism. 

'Eight items regardless of what they were from Coles should not cost you $72,' she said.

She said the only reason she shops at Coles is to buy items she can't get at Aldi.  

'Otherwise I would not step foot in that place.'

A Coles spokeswoman told Daily Mail Australia they encouraged customers to do their own price comparisons.

'We are always working hard to deliver value to our customers, particularly with ongoing cost of living pressures including higher mortgages and rents, energy and fuel,' she said.

'We know customers are always looking for great value and Coles pricing always aims to deliver this. 

'We offer great value from the thousands of weekly specials to longer term Down Down promotions which provide our customers price certainty on specific products for an extended period of time.

'All of our current prices are clearly available on our website, our app and in-store and we know customers look at these every day. 

'We welcome our customers doing their own price comparisons; however, in the case of this video, it is unclear whether like-for-like products are being compared.'
