It depends how far through the process you are.
After placing an order, there's normally a 3-hour window before it will be processed, so you'll be able to make changes to the designs or images during this time. Please note, it is not possible to change the shipping method, quantity or add additional items to the order once its been submitted.
If you need to change the designs go to "Your Account", then "Order history" and look for the order you want to change. Please note that the editing window is not available on next day or 2 day delivery options.
If the order is marked "Printing" or "Dispatched", it's usually too late to make changes
