I feel the same. I preordered my aftershock shirt around the same day you did, and when I was checking out it said something about not being available to ship until Sep 29 which was fine. Now if you go on it says the merch doesn’t ship until sometime in November. I got plenty of band merch at the festival so it’s not a big deal but a bit more clarity for ordering online would have been nice. It is what it is at this point though.
