I'm guessing it will show up next week for me for the Austin show. Regular tickets go on sale next Friday, so I would imagine the presale will be a few days earlier in the week.
@Aron fan pre-sale starts in less than 10 minutes I think for all the shows. they had people sign up for email with code but it seems to not have gone out yet.
That must be the pre-presale from the band. ACL Live usually has a presale a few days earlier, which I often skip because they are usually for general admission tickets only. I tend to shoot for Mezzanine level seats at that venue, but, for a S-K show, I'm thinking I might want to be down with the masses. But, no email as of yet, and I did sign up through their site a week or so ago.
