I was in Chemist Warehouse at Doncaster today, and they were marking down all vitamins / minerals in all brands down by 50% from the RRP. It officially starts tomorrow - though I can't find anything on their website.
Additional info from other ozbargainers:
Includes the following brands: Blackmores, Naturopathica, Swisse, Cenovis, Bio-glan, Bioorganics, Nature's own, Nature's way
It seems like its instore only.
It appears to be national, and ends next Sunday
Pretty sure it's national, all the vitamins on their website are marked down to 50% of their RRP.
awesome deal, i'm just about to finish my current bottle
