You can change your delivery mode by logging into My Account and clicking on the "Edit Shipping" link located just under the Delivery Address.
This may result in a balance due on your order which will need to be paid before your order will ship out. You'll be able make payment in My Account if this is the case.
If the change results in a refund, we'll submit that shortly after the order has shipped.
*Note: For extended production orders, you'll need to contact us to upgrade this for you. Keep in mind that there is no guaranteed delivery date for orders with this type of production regardless of the upgraded shipping mode.
