Which supermarket is cheapest in Australia?

Aldi is typically cheapest for everyday staples — often 10–30% lower than Coles or Woolworths on comparable items. However, Coles and Woolworths half-price specials can beat Aldi on specific products each week. Use CartSavvy to compare current prices across all stores before you shop.

Is Aldi cheaper than Coles and Woolworths?

Generally yes for the items Aldi stocks, but Coles and Woolworths rotate half-price specials that can undercut Aldi on a given week. CartSavvy shows unit prices ($/kg, $/L) across all three so you can compare like-for-like rather than just pack price.

What is unit pricing and why does it matter?

Unit price is the cost per standard measure — $/kg, $/100g, or $/L. It lets you compare two different pack sizes fairly. CartSavvy displays unit prices for every product so you always know the true cost per gram or litre.

Does CartSavvy compare Harris Farm prices?

Yes. Harris Farm products appear alongside Coles, Woolworths, and Aldi on CartSavvy's grocery page, including unit prices and any active discounts. Harris Farm often stocks premium and organic lines not found at the major chains.

Are Coles and Woolworths specials real discounts?

Not always. Some items are marked as on special but haven't been sold at the higher was price in weeks. CartSavvy flags these with a possibly a fake discount warning when the data suggests the reference price is inflated.

Can I compare Asian grocery prices in Australia?

Yes — CartSavvy compares prices at uMall, Asian Pantry, eBest, and JFC Online alongside the major supermarkets. Filter by All Asian Stores to see deals specific to Asian grocery retailers.

How often are prices updated?

Prices are indexed fresh each morning from Coles, Woolworths, Aldi, Harris Farm, and all 15 stores CartSavvy tracks. The last update time is shown in the footer of every page.

How do I get price drop alerts?

Sign up for a free CartSavvy account, then click the bell icon on any product card. We'll email you when that item's price drops at any of the stores we track.
