Sorry, just learning that meant Get It Now. I don't know how to change my listing or to add that right now. I will try to figure that out asap. I also didn't get this message right away. I will respond much faster in the future.
I figured it out. This is my first listing. You can't do a GIN until you have your seller wings, which you don't get until after your first listing. So I can't do that. Sorry.
