Custom Ink generally has a policy that allows for modifications to orders, but the ability to add items to an existing order may depend on the current status of that order. If an order has already been processed or is in the production stage, it is likely that no further changes can be made. However, if the order is still in the design or checkout phase, it may be possible to add additional items.
In such cases, it is best to check the order status through the Custom Ink website, where users can find options to modify their orders. It is important to act quickly, as changes need to be made before the order progresses too far in the production process. If you wish to add items, look for the necessary options on the website and follow the prompts.
To get the most accurate and up-to-date information, it may also be helpful to review the Custom Ink website's FAQ section or the order management area for specific guidance regarding your order's ability to accommodate additional items.
