It is not explicitly mentioned whether different purchase orders (POs) can be mixed within a single carton. However, for pallets, each e-commerce shipment carton and pallet must contain one SKU, and mixed pallets must be properly labeled. This implies that mixing POs may not be preferred or allowed in individual cartons.

Mixed pallets are allowed but they must have a label provided notating item numbers and quantities included on each pallet. All ecom item numbers must be visible from the outside to assist with quick receiving.

Yes, SKUs can be mixed on a single pallet, but they must be clearly labeled as mixed. The SKUs should be separated from each other on the pallet and not intermixed.

SKUs cannot be mixed within a single carton. Ecom goods must be packed one size/color per carton, and the carton should contain only one ecom item number. Mixed colors and sizes will lead to the depot refusing the PO. For pallets with mixed SKUs, a label notating the item numbers and quantities included on each pallet must be provided.
