Including Boxes in Shipping Costs or Sale?


I have some dahlquist speakers that I was planning to auction off on this site. I can see that shipping is automatically calculated based on the buyers location and selection of shippers. In my case I do not have the original boxes so either need to have them built or buy something standard. My question how to include the box costs into the sale? Do sellers normally include the box into the selling price or is there a way to include in the shipping costs?

Rockvirgo - that's one of the most informative responses I've seen in a long time. I never understood why the seller would be the one to initiate a claim in the event of a shipping misfortune. Thanks for sharing all this in a clear way.
