If you think it is impossible to feed a family of four for less than $80 a week - that's about $11 a day - a discount supermarket chain and a budget-busting mother believe they're up to the task.

After nine months of planning, they're signing an agreement to save Australian families a fortune.

NQR CEO, Aaron Fitzgerald is offering up to 80 per cent off the recommended retail price of packaged goods.

“If they shop here first they'll make a great saving," Fitzgerald said.

• Saving money on your shopping

There are 19 stores in Victoria and online deliveries across the country.

“It's a $12 flat fee to all metro cities except for Perth which is $15," Fitzgerald said.

Cheapskates author Cath Armstrong will create weekly menus which will be updated on the NQR website.

“It’s a way we can both save Australians mega-bucks on their groceries," Cath said.

Packaged goods can be bought at your local discount supermarkets like NRQ, Aldi and Costco. You will need to see your local grocer and butcher for fresh produce.

“Never shop without a list or it'll blow your budget out of the water," Cath advised.

Today Tonight went shopping for the first week's menu and the bill for three meals a day, for four people, for an entire week, came in at $75.72.

For around $11 a day, Cath catered for Wendy Gower's family. Mother to two teenage girls, Wendy is constantly looking for ways to create tasty, healthy meals on a budget.

And the verdict: “It’s good, it’s easy, it's cheap and it’s given me different options for cooking at home for my kids," Wendy said.
