Buy Delivery Services does not support the use of different packages for separate parts of one product. This means that it is not possible to buy separate delivery with different labels and tracking numbers for individual parts or pieces of one product listing.
To buy delivery for separate products in one order (individual line items, not multiple parts of one product), buy delivery for the first item by including the quantity of each item in the package. Then, return to the Order Details page to buy delivery for the next item. Repeat for other items as needed.
From your seller account, click Orders, click Manage Orders and then click the Buy Delivery button to start the process.
