You are making the shipping process way too complicated for other people to comprehend. You can box this up yourself and bring it to the post office to be weighed. Then use the usps online calculator to determine the price with the bidder or winner's zipcode. Why should winner have to pay to ship the item AND pay to ship you the shipping box? Makes no sense. They would need to know how much the item and box and packing materials weigh to get the right postage on the box they ship to you.
