Unfortunately, we cannot add pre-order products to existing orders as we have order processing priorities set to order numbers. As this is an automated system, by adding the pre-order product to your order, we might be taking the piece from another customer that placed their order later than you, however, purchased the pre-ordered product before you've asked for the amendment.
If you have multiple open orders, would like to merge them into one and have a pre-ordered product on one of them, we will be merging your orders into the one that already has the pre-order product on it to prevent the issue described above. The same issue occurs when a product is on pre-order and we offer different versions of it in our webshop (Acetal/Plexi; Black/Silver, etc) and you'd like to swap the pre-ordered product for another version.
In case you'd like to make any of the above-described changes, we will offer to cancel your order so you can place a new one to ensure we stay true to all the customers that have ordered a pre-order product at a certain time. To contact Sales and Shipping Support, submit your request via our contact form. In the event that you already have an open request ticket, please allow us to review it and reply to it before you close it, as we will not be able to respond to it or make any changes you require to your order if the request is closed.
