The Campbelltown Autobarn Store put up a 20% off Storewide only an hour ago.
I tried to call their Head Office to confirm if it was state-wide, but wasn't able to get through twice.
I'm pretty confident this will pop up all over the place for Black Friday, and will edit the post once it's confirmed.
PS: I've taken a snap of the signage, and uploaded it, but I can't seem to get it to show up.

I can confirm that this is a 20% off Storewide promo, and an extra 25% off Rhino Rack
