Well, you can offer free shipping or ask for the buyer to pay for the shipping. If you offer free shipping & someone wins the auction, you can't tell them you want them to pay for the shipping after the auction is done. You have to put it in the auction. I've come across people that do that. The you just pack it up & go to the post office(: I'll be bidding on this(:
Just get a big padded bag or the medium priority box or something similar. I used to sell bridal gowns on eBay for many years after I closed my bridal shop.
