Free shipping for just the reshiram? Or this whole auction? If it is just reshiram and you'd put it up in another auction let me know when you have :) plus there is a reply button for you to select when replying back to comments, lets me and anyone else know when the question has been responded too :)
You should just be able to go to the auction, if your on the Listia phone app there should be a "pencil" at the top of the screen that will give you the option to edit, on a computer you go to the listing and there should be and edit button. I'm sorry I keep being a pain..
