School Lunchbox Basket: Save Up to $13 a Week

Packing school lunches every day adds up faster than you'd think. Bread, cheese, a piece of fruit, something sweet, do it five days a week across a few kids and you're looking at a decent chunk of your grocery budget before you've even thought about dinner.

We priced 11 lunchbox staples and ran the numbers. The results are worth a look.

What the basket costs at each store

Shopping the full basket at Coles this week will set you back $54.80. That's the most expensive option by a fair margin.

Woolies comes in at $45.90, which is $8.90 cheaper than Coles for the exact same list. Aldi lands at $47.19, though one item in the basket isn't stocked there, so that's not a completely like-for-like comparison. IGA sits at $51.80, also missing one item.

If you cherry-pick the cheapest price for each item across all four stores, you'd pay $41.35. Compared to doing your whole shop at Woolies (the cheapest single-store option), that's a saving of $4.55.

So the honest headline is: Woolies wins as a one-stop shop, Aldi is close behind, and Coles charges noticeably more for this particular basket.

Where the biggest price gaps are

A few items do most of the heavy lifting here.

Bread is the first one. Two 700 g loaves of sliced white bread cost $3.10 at Woolies this week. The same quantity at Coles is higher. Bread is something most families buy every single week, so even a small per-loaf difference compounds quickly over a school term.

Yoghurt pouches are where Aldi really shines. A 6-pack costs just $0.75 at Aldi. That's an extraordinary price for a lunchbox staple kids actually eat. If you've been buying yoghurt pouches at Woolies or Coles without checking Aldi first, this one might make you wince a little.

Ham is another standout. Sliced ham (200 g) is $1.99 at Woolies, which is the cheapest in the basket comparison. Ham is probably going into sandwiches multiple times a week, so this matters.

Tuna in springwater (a 4-pack of 95 g tins) comes in cheapest at Aldi for $3.29. Not every kid will eat tuna at school, but for older kids or as an easy protein option, it's solid value.

Where the prices are basically the same

Not everything has a dramatic story.

Vegemite (220 g) is cheapest at Coles for $4.00, and the price doesn't vary wildly across stores. A jar lasts a while anyway, so it's not a weekly decision for most people.

Sultanas (6-pack) are also cheapest at Coles at $2.50, with prices elsewhere not far off. Same goes for muesli bars (two 6-packs), which are cheapest at IGA for $2.50 but aren't dramatically different elsewhere.

For these items, it genuinely doesn't matter much where you buy them. Don't stress about it.

Is the cherry-pick worth an extra trip?

This is the honest question, and the honest answer is: probably not, for most people.

The cherry-pick saving over Woolies is $4.55. That's real money, and over a school year it adds up. But to get it, you'd need to visit at least three stores: Aldi for the yoghurt pouches, tuna and cheese, Woolies for the bread and ham, and then Coles or IGA for a couple of items.

That's an extra 30-45 minutes minimum, plus petrol. If your time is worth anything, the maths doesn't favour it.

The better approach for most families is to do your main shop at Woolies (the cheapest complete basket), and add Aldi into the rotation when you're already passing one. The yoghurt pouches alone justify swinging through Aldi if it's on your way. Buy a few weeks' worth of tuna and cheese while you're there and you'll claw back a decent saving without any extra effort.

If you're already an Aldi regular, great. The basket is only $1.29 more than Woolies when Aldi stocks everything, and some weeks you'll find Aldi cheaper overall.

Fruit deserves its own mention

The two fruit items in this basket have some of the most interesting prices.

Apples (1 kg) are cheapest at IGA for $1.10 this week, which is genuinely cheap. That said, fruit prices move around constantly depending on season and store promotions, so don't count on that price holding. Check before you go.

Mandarins (1 kg) are cheapest at Coles for just $0.35. Yes, 35 cents. That's a promotional price and almost certainly won't last, but if you're shopping this week, load up. Mandarins are perfect lunchbox fruit, easy to peel, no mess, kids eat them.

Fresh produce is where price comparison sites like this one are most useful, because the prices genuinely change week to week. What's cheapest today might not be next Tuesday.

Who should shop where

If you've got a couple of kids in school and you're doing a full weekly shop, Woolies is the safest single-store option for this basket. You'll get everything on the list, pay $45.90, and be done with it. That's $8.90 less than Coles for the same items with no extra effort.

If you live near an Aldi and you're not already shopping there, the yoghurt pouches and tuna alone are worth building it into your routine. Aldi's prices on packaged goods like these tend to be consistent, not just one-week specials.

Coles is the hardest to recommend for this particular basket. On these 11 items, it's the most expensive store by a clear margin. That's not always the case across every category, but for lunchbox staples it's not where you want to be doing your regular shop right now.

IGA fills a gap on a couple of items (muesli bars and apples are cheapest there this week), but as a full basket shop it's $5.90 more than Woolies and missing an item. It makes sense if IGA is your local and convenience matters, but you're paying for that convenience.

Families going through two or three loaves of bread a week and packing five lunches a day will feel the Coles-versus-Woolies gap most acutely. Singles or couples packing one lunch occasionally won't notice it as much, but the Aldi yoghurt pouch price is almost offensively good regardless of household size.
