Aldi has Cucina Penne 500g for $0.89 today, a cent under Coles and Woolies (both $0.90) and a full $2.71 less than IGA's $3.60. For a pantry staple you're reaching for two or three nights a week, that gap adds up fast. Chuck a few packs in your trolley while you're there, penne holds up well to chunky meat sauces, baked pasta dishes, and the kind of throw-it-together school-night dinner that needs to be on the table in 20 minutes. At under a dollar, there's no reason to pay more anywhere else.
