A savvy shopper has revealed a simple Monday trick that could slash your weekly food bill by as much as 60%.
The money-saving hack involves using food delivery apps instead of supermarkets – but only on one specific day of the week.
That’s because apps like Just Eat, Deliveroo and Uber Eats roll out some of their biggest grocery discounts on Mondays, when demand is at its lowest.

Deals can include up to 60% off fruit and veg, as well as 50% off essentials like dairy, meat and ready meals.
The trick was shared by deal-hunter Alisdair Baker, 51, from Aldershot, Hampshire, who says he now plans his weekly shop around it.
He explained that Monday is typically one of the quietest days for takeaway orders, prompting apps to offer deep discounts to attract customers.

As a result, shoppers can often get groceries cheaper than in-store – even after factoring in delivery and service fees.
Alisdair said he has even stopped buying certain items at the supermarket altogether, choosing instead to wait for the Monday deals.

He told What’s The Jam: “I worked out that I could get my fruit and veg cheaper on a Monday through food delivery apps than I could at my local supermarket, and the savings were too good to ignore.”
What started as a simple test quickly became part of his weekly routine.
He said: “What started as an experiment with Just Eat’s 60% off fruit and veg promotion has now become part of my food budget.”

The savvy shopper, who posts hacks to his online blog, said the biggest savings come from “deal stacking” – combining multiple offers at once.

This can include app discounts, loyalty schemes like Co-op membership deals, cashback websites such as TopCashback, Quidco and Rakuten, and gift card cashback apps like JamDoughnut.
By layering these deals together, shoppers can dramatically cut the final cost of their groceries.
He said: “That means you’ve got the special deal prices, instant cashback from the gift card, and sometimes cashback from a second site as well – so it’s multiple layers of savings on one shop.”
Alisdair also recommends checking each app individually, as the offers can vary week to week depending on what retailers are promoting.
He said: “One week, Just Eat might have incredible fruit and veg, another week Deliveroo might have better meat and dairy deals – so it’s worth checking all three.”
While Monday tends to offer the biggest savings, he noted that midweek deals can also be worth watching.

He said: “Wednesday is worth knowing about too, as Just Eat runs a 50% off grocery essentials deal, which can be just as valuable.”
In one recent shop, he managed to get £60 worth of groceries for just £39 using a combination of offers.
Even after fees, he said it still worked out cheaper than buying directly in-store – and arrived within 30 minutes.
Despite the huge discounts, he warned shoppers not to get carried away.
“The whole point is to save money on things you’re going to buy anyway – not to fill your basket with bargains you won’t use,” he said.
