Prices between supermarkets will vary depending on distributor pricing (what a supermarket pays to source and stock a particular product), what they source directly from manufacturers, location (i.e. regional or metropolitan) and simple supply and demand. Our survey found that Aussies who shop at IGA − an independently-owned and operated supermarket – tend to pay less for groceries per week than those who shop at Coles and Woolies. ALDI shoppers also pay less for groceries than Coles and Woolworths customers, even when splurging on Special Buys.

Top 10 tips to save money on groceries

  1. Make a grocery budget: Set yourself a food budget for the week. The easiest way to do that is to allocate about $50 per person in your household. Once you have a concrete figure, work your grocery shop around that, and try to stay on budget.
  2. Write a shopping list: Similarly to having a budget and sticking to it, you should write down a shopping list of everything you need before you head to the shops. Check your pantry and fridge first to make sure you’re not doubling up on anything. Once you have a list written down, buy only what’s on that list and nothing else. Sorry, that Kinder Bueno will need to go back on the shelf!
  3. Get ‘appy’: There’s an app out there for practically anything, including for saving money on groceries. Apps like Trolley Saver and Half Price compare and track down specials across the major supermarkets like Coles, Woolworths and ALDI. Both are free to download on iOS and Android.
  4. Know the system: Did you know most produce and perishable products like meat and milk are typically marked down the day before their ‘best before’ date? Or that manufacturers/brands pay a premium price to have their products on shelves at eye level, while home brands are typically ‘pushed’ down on the lower shelves? Hack the system to your convenience friend!
  5. Use supermarket rewards programs: Woolworths has the Everyday Rewards card and Coles has flybuys, which allow you to collect loyalty points for dollars spent, redeemable for discounts on future shops.
  6. Check the unit price: ‘Cheaper’ doesn’t always mean good value. The best way to make sure you’re getting bang for your buck on any product is to check the unit pricing. It’s a mandatory labelling system which basically tells you the cost per litre, per kilogram (or whatever unit of measurement) of what you want to buy.
  7. Buy supermarket brands: You can save a few bucks at the checkout by ditching big brand names for private supermarket labels, especially when it comes to non-perishable products like pasta, rice, canned beans, etc. Our survey found nearly half of Aussies (45%) believe supermarket private labels are good quality.
  8. Don’t pay full price if you don’t have to: Check out the supermarket weekly catalogues for promotions and discounts, to see which items on your shopping list you can buy for less. As good practise, always keep your eyes peeled for sale signs whether you’re shopping instore or online.
  9. Buy in bulk. Necessities such as toilet paper and pantry items are often cheaper to buy in bulk than in single packets. Do the maths and see if you can shave a few dollars off your shop that way.
  10. Reduce food waste. You can save big bucks by re-purposing or freezing leftovers, instead of throwing uneaten food (and money) in the bin.
