Aldi's got Inner Goodness Oat Milk 1L for $1.65 this week, while the exact same size will set you back $5.50 at Coles. That's a $3.85 difference for a pantry staple most households are buying every single week. If you're going through a carton or two in your morning porridge, school lunches, or the daily coffee, it adds up fast. Worth grabbing a few while you're there.
