With the launch of Supercheap Auto Trade, overheard the lady mention an additional 10% off Trade Prices currently - code seems to work for every location for click and collect not specific to Penrith (thankfully).
There does not seem to be any restrictions, so security cameras, stereos, oils, car parts, special orders, and basically any other Supercheap Auto deal on OzBargain, you will receive an additional 10% off including sale items.
Anyone with an ABN can register for a trade account, this includes sole-trader, you technically don't have to be a "tradie", no verification required.
Enjoy.
read the deal description, that is what it is there for…
