Yes, you can order multiple items in the same order as long as they are produced at the same print partner.
We will ship the multiple items together where this is possible, except for the cases mentioned here.
Note: If you place an order containing items from different product categories (e.g. a photo book and a canvas) these might be produced by different print partners and you will receive an error ("More than one production locations") when trying to place the order. In this case, please place separate orders for the different items.
