Morrisons will start selling its cheaper budget ranges across its 500 smaller convenience stores.
In a move believed to be the first in the UK, the supermarket chain will be stocking these cheaper products in Morrisons Daily shops over the coming weeks.
The rollout will start with 10 products from the Savers range, including essentials such as toilet rolls, washing up liquid and skimmed milk.
In the coming weeks, a further 30 items will hit the shelves such as eggs, ham, juice, butter, cheese and mince.
The 'big four' supermarket chain has converted around 500 McColl's convenience stores into Morrisons Daily shops, since buying the rival out of administration in May last year.
The overhaul resulted in prices going down by about 12% as it brought its own product ranges into stores, it said.
Morrisons boss David Potts said: “Inflation is stubbornly high and the cost of living is showing no signs of reducing.
"Speaking plainly, the reason that convenience stores don’t stock entry price point products is because they make very little, if any, money and do not fit with the significantly higher cost structure of convenience stores.
"But customers - especially those living in areas without easy access to a supermarket - have told us how much they would appreciate it at this difficult time and so we are doing it.”
Morrisons has recently relaunched its Savers range, adding 56 new lines and redesigned its packaging to help its customers have food at affordable prices.
Consumer watchdog Which? have been calling on supermarkets to stock budget ranges in small stores after an investigation earlier this year found these items are hardly ever stocked in smaller supermarket shops.
This is despite the fact that two-thirds of those with a household income under £21,000 shop in them at least once a week.
Sue Davies, Which? head of food policy, said: "Morrisons deserves praise as the first big supermarket to show there is no barrier to putting budget ranges on the shelves of all stores for the same price.
"We look forward to seeing the full range that Morrisons will be offering that should ensure households on tight budgets can cook a range of healthy meals.
"Other supermarkets should follow this example by stocking a range of budget lines that support a healthy diet across branches, including smaller convenience stores - with a particular focus on areas where people are really struggling with the cost of living.
"All supermarkets should also make pricing more transparent - including on promotions and loyalty card offers - so shoppers can easily find the best value products."
