It's always best to deliver orders on-time, but we recognize that there are situations where unforeseen edits or re-takes are required, or, where both buyer and seller agree to extend the delivery terms. If you and the buyer agree to the extension, then we have no problem with it. You can submit an order modification request to extend the delivery date using the "Modify Terms" link at the bottom of the order page. If something arises that you are unsure about, don't hesitate to contact us.
