Priceline Doncaster (Vic) has Iluka skincare (by Natalie Imbruglia) for $2.50 at the moment as a part of their Pink Dot Sale. I've linked to their website so you can see the range but the products aren't $2.50 there.
Quite a bit of stock left of the following: Rosehip Oil, Illuminising Pearl Primer, Foaming Cleanser, Cream Cleanser, Lip Serum, Eye Serum, Face Polish and Light Day Cream.
Items scanned at higher prices (some $12 and some $20) but the display says they are definitely $2.50.
