It’s very simple and saves you a lot of money. You can collect all your cartons any time within 7 days of your move. After you are done using them, you can return them anytime within the next 28 days after your move. Please note that you just need to ensure that the boxes are well looked after. We only levy a $5 holding deposit per box but you are billed for whatever cartons you keep even after the 28 days expire.
