For the prepaid FedEx return labels you receive from us, you have until 30 days before that label is no longer usable. However please make sure to use the label in the return period available to you from the delivery date. If in the end, you do not use our label to return the item, you will not get charged for the cost of the label. You will only be charged for the prepaid label if you end up using it to return the item. If you decide to use another label, we will offer you a full refund on your order upon receiving the package(s).
