Generally you can change your delivery address within 24 hours. Be sure to contact us immediately with your order number and the correct address. The more information you provide, the faster we can change your information. While we cannot guarantee that we will receive your order in time before it begins processing, we will do our absolute best to make the requested changes. Be sure to write "Urgent: Change Order Details" in the subject line. All other titles may cause delays in the delivery of your order. Please note that your order may have already been shipped. In that case, we can't send you a new one, so it's best to contact the postal service.
