Hot Lunch Thermos Basket: Aldi Wins at $39.92

Sandwiches are fine until they're not. By week three of the school term, plenty of kids are quietly chucking their lunch in the bin rather than eating cold Vegemite on white for the hundredth time. A thermos changes that, leftover bolognese, a cup of soup, some cheesy pasta, and the groceries that fill one are dead simple. We priced this exact basket across Coles, Woolies, Aldi and IGA to find out where your money goes furthest.

What Does This Basket Cost at Each Store?

Here's what you're looking at for an 11-item thermos lunch shop:

• Aldi: $39.92 (one item unavailable, soup pouches)
• Woolworths: $41.50
• Coles: $41.55
• IGA: $49.25

Aldi comes in cheapest among stores that can fill most of the basket. Woolies and Coles are almost identical, just five cents apart, which in practice means nothing at the checkout. IGA is a different story: $49.25 is nearly $10 more than Aldi for the same items, and that gap is hard to talk yourself out of.

The cherry-pick number, buying each item from whichever store has it cheapest, lands at $34.13. That's a $7.37 saving against the Aldi total, which is the best single-store price.

Where the Biggest Price Gaps Are

Beef mince is where stores earn or lose your loyalty fast. Aldi's 500 g pack sits at $6.49, and it's the standout savings point in this whole basket. Mince is the workhorse of thermos lunches, bolognese, mince and pasta, shepherd's pie filling, so getting it cheap matters.

Instant noodles (5 pack) are $1.79 at Aldi. That sounds trivial until you remember these are a weeknight dinner and a thermos filler in one. Kids will actually eat them. The price across other stores creeps up noticeably.

Yoghurt pouches (6 pack) are where Aldi really runs away with it: $0.69. That's not a typo. Yoghurt pouches at the other supermarkets cost considerably more, they're the kind of item where the Aldi private-label version does exactly the same job for a fraction of the price.

Pasta sauce (500 g) at $1.59 from Aldi and penne at $0.89 means your pasta base costs $2.48 total. Add the mince and you've got a bolognese filling for under $9.

Where Prices Are Basically the Same

Not every item has a big gap worth chasing. Tasty cheese (250 g) is cheapest at Coles at $4.20, and Woolies isn't far off. If you're already at Coles for other reasons, this one's a non-event.

Apples (1 kg) are $3.69 at Aldi, and this category tends to move week to week with whatever's in season. In winter, you'll often find Granny Smiths and Pink Ladies at competitive prices across the big two as well.

Soup pouches (4 pack), the one item Aldi doesn't stock, are $1.70 at Woolies. Given the rest of this basket skews hard toward Aldi, Woolies wins exactly one line item here, and it's a small one.

Is the Cherry-Pick Worth an Extra Trip?

Honest answer: probably not for most households.

The cherry-pick saves $7.37 over shopping at Aldi alone. That's real money across a month, but it means stopping at two or three stores. Factor in petrol, parking, and the 20 extra minutes you won't get back, and the maths softens considerably.

The one exception worth considering: if you already pass an IGA or Woolies on the school run, grab the dinner rolls ($1.30 at IGA) and the peas ($1.95 at IGA) while you're there, and do the rest at Aldi. Those two items are cheapest at IGA, and the stop doesn't cost you anything if it's already on your route.

Otherwise, just do Aldi and know you're within $7.37 of the theoretical best price without the faff.

Who Should Shop Where

Aldi households, if you already shop at Aldi, this basket slots in easily. You'll get 10 of 11 items without needing to go anywhere else. The one gap (soup pouches) is minor, make a batch of homemade soup and freeze it, or grab a four-pack at Woolies during your next top-up shop.

Coles/Woolies regulars, you'll spend almost exactly the same either way ($41.50 vs $41.55), so don't stress about switching. Pick up the cheese at Coles if you're there, and know that Aldi's mince and yoghurt pouches are noticeably cheaper if you ever find yourself nearby.

IGA shoppers, IGA wins on dinner rolls and peas, two fairly cheap items. For everything else in this basket, the IGA price is the highest. If your local IGA is the only option and you genuinely can't get to an Aldi or a major, it's worth looking at what you can buy in bulk or substitute with home staples.

Budget-first families, CHOICE's most recent supermarket basket survey found Aldi consistently cheaper across comparable baskets in most states, and this hot lunch shop backs that up. Eight of the eleven items are cheapest at Aldi. If keeping the weekly bill down is the priority, Aldi is where you want to be for a basket like this.

A thermos lunch isn't just a sandwich workaround, over a school term, it's also a food waste fix. Leftover pasta and mince that would otherwise sit in the fridge until someone throws it out becomes tomorrow's lunch instead. At $34 to $40 for the whole week's thermos-filling groceries, that's a decent return on one after-school task.
