Coles has the above mentioned items at half price in this week's catalogue.
The Hask Argan oil shampoo and conditioner are my current favourites. It's "Free of: sulfates, parabens, phthalates, gluten, drying alcohol and artificial colours. Not tested on animals." A bit pricey at full price but happy to stock up when half price :)
Hask is not discounted to 1/2 price that often, but it happens to also be half price at Priceline at the moment.
Dove 1L Body Wash is half price…. nice! This stuff hardly ever goes half price.
