You'll want to change your shipping to Free from local pickup only then and it's no longer credits -- its the cryptocurrency XNK for about the last 3 months :)
Sure no problem :) Click on 'edit' your listing, scroll down to "Delivery" and click on "item will be shipped" then there's a drop down box that give the options :)
You don't have the option to GIN (get it now) -- you have to have completed 5 listings with positive feedback to get your Sellers Wings before you are able to do GIN. If you want a certain amount for this then you need to change your start bid for what you're willing to settle for. But you can't do that now since someone placed a bid and there's 6+ days left on this listing :)
