There should be a return label in the package with your delivery, if you are missing this then please contact us with your order details. (Unfortunately not to Canadian customers). Please note that we only provide return labels for the original order. Subsequent repeat returns will need to be shipped at the customer's cost.
If your order does not qualify for free return shipping then please just send it back with whichever postal service is most convenient for you. We recommend recording the tracking reference as you're responsible for the item during transport.
