Hi. If you open up your auction page you'll see where you can edit it. Push 'edit', then scroll down towards the bottom, under where the map of where you are shows & under that there is a small box to the left that says something like 'advanced options'. Push that and it will be in that section. Unfortunately, you may need to wait to get your seller's wings badge for that option. Also, when you list a GIN they charge a percentage of what your GIN list price is. Another unfortunate thing is that I only have 5854 credits as of now, so I'll get outbid before my credits are available. Lol.
