The pandemic has meant that people are looking for savings where they can, including their grocery shopping.

One of the best places to save some extra cash is the supermarket, and consumer group CHOICE has confirmed whether Coles, Woolworths or ALDI offer the best prices with a survey of 152 products.

CHOICE found that ALDI was on average 20 per cent cheaper than Coles or Woolworths.

“We were surprised that there was such a discrepancy,” says Margaret Rafferty, managing editor of CHOICE.

“I think in some products you could save up to 50 per cent more by shopping at Aldi.”

15 items were at least 35 per cent cheaper.

ALDI was thrilled with the news.

“From somebody as credible as CHOICE, it’s a great reassurance to us and our customers that we’ve got the best price,” said Andrian Christie, Aldi’s customer interactions director.

ALDI also took out the most categories in CHOICE's home brand comparison last month, taking top spot for best tomato sauce and best tea.

However, if you don't have an ALDI nearby, you can still save money at Coles or Woolworths.

“There were a few (items) where Coles and Woolies were cheaper. It wasn’t universal,” Rafferty said.

For example, sweet treat Clinkers cost $1.74 per 100g at ALDI but only $1.67 at Coles and Woolworths.

The best advice to follow is to look at the cost per amount.

“Just look at the unit pricing. Compare that and that will tell you if you’re getting the best price,” says Christie.
