Aldi has OMBRA Kids Sunscreen SPF 50+ 250ml for $3.99 right now, which is $1.51 less than the $5.50 you'd pay at Coles for the same size. If you've got kids heading outside this week, school sport, weekend footy, a day at the beach, this is a pretty easy trolley add. Most name-brand kids SPF 50+ options sit well above $10, so $3.99 for a 250ml tube is a solid deal without having to hunt for a special. Grab a couple while it's in the Aldi aisle.

Woolies has the WaterWipes Baby & Newborn Sensitive Wipes 60-pack at $5.50 today, but you'll pay $3.50 at Coles for the same thing, and just $2.50 at IGA. That's a $3 difference on a single pack, it adds up fast when you're burning through wipes daily with a newborn. WaterWipes are popular with parents of sensitive-skinned bubs because they're made with 99.9% purified water, so they're about as gentle as it gets without just using wet cotton wool. If you're already doing a Woolies run, it might be worth swapping stores or picking these up at IGA while the price gap is this wide.

Coles has the Springleaf Aussie Kids Gummy Lutein 200g (80 pack) for just $5.00 today, down from $25.00, that's $20 off a supplement that usually sells at full price without a second thought. These pineapple mango flavoured gummies are designed to support kids' eye health and brain development, so they're the kind of thing you'd pick up alongside the school lunch staples rather than making a special trip. Kids' vitamins and supplements have been creeping up in price across Coles and Woolies this year, so grabbing 80 servings for a fiver is genuinely good value. Toss a pack in the trolley while the price is there.
