Great deal on Penrite semi-synthetic oil in 6 litre size and engine oil flush if this suits your vehicle (ie. Falcon/Territory 4.0L, and some mainly pre-2003 vehicles of other makes).
You can also check price online, have to select "Add Combo to Cart" and also select your store. Valid in VIC but might not be all states.
Not sure how long stores will have stock, but I got some for my old Falcon ute.
Has a limit purchase limit of 3 or maybe 4 per person in store (can't remember).
EDIT: First post, be gentle please.
