Drove past and saw they were advertising it, seems like an ongoing deal rather than special.
It's a good price for a Tyre Puncture Repair in Melbourne.
I paid $30 recently, wish I saw this when I needed it.
Edit- OzBragain confirmed with the store it's an internal patch repair, not a push in plug.
Interesting deal.
It's probably not really an impulsive type of purchase like most of the things on OzBargain.
