The above offer showed up in my Facebook Feed as a sponsored post from 7-Eleven Australia's official Facebook page. It has since disappeared and I haven't been able to find it again, so just posting it for information only (happy if someone in the area wants to go into the store to confirm). If I see it again, I will take a screenshot and update this post.
Edit: Found it again, enjoy.
lol so its not actually a deal… it's a myth
