Aldi's got Inner Goodness Oat Milk 1L for $2.99 this week, while Coles has the same size sitting at $5.50. That's a $2.51 difference for something most households are pouring into coffee and cereal every single morning. If you're already doing an Aldi run, it's worth throwing a couple in the trolley. It keeps well in the pantry, so stocking up makes sense.
