This has got to be a pricing error, but it's interesting nonetheless. Big W currently has Gears of War 4 for a cheeky cent on its online store. It's showing stock and you can get it delivered, but it'll cost you $3.90 in shipping (so it'll come to $3.91). Picking up in store is also an option, although no stores around me had any stock. It's unclear what will happen if this is proven to be a pricing error. Sometimes its honoured, or other times it'll be refunded with a credit for the inconvenience.
