For pre-order campaigns, changes in product size and/or order cancellations must be processed before the end of the pre-order campaign. After the campaign has ended, we are unable to make these changes to the order.
We are able to make updates to the shipping address and other customer information on the order up until the order is shipped. After the order has shipped, we will no longer be able to make these updates on the order.
Contact our Customer Happiness team with any questions regarding changes in product size, shipping address, cancellations, etc. for pre-order campaigns.
