As long as the shipping label for your order has not been printed, you can still edit your shipping address.
To see if you can still edit your shipping address, please login to your seetickets.us account and click the blue DETAILS button next to your purchase.
If you see the Edit Shipping Address link next to your address, then you can still edit it.
If it's not there, then it's too late. Sorry but we do not re-ship tickets.
