Aldi has Asia Green Garden Soy Sauce 500ml for $1.79, which is 11 cents under Woolies' $1.90. That's not a headline-grabbing saving on its own, but soy sauce is one of those things you grab every few weeks without thinking, so you may as well grab the cheaper one. It's a solid all-rounder for stir-fries, fried rice, marinades, and the classic dipping sauce next to your weekend dumplings. At under two bucks for a 500ml bottle, it's hard to argue with.
