ALL Nature's Way products 50% off (with the exception of maybe one or two and I mean that) at Chemist Warehouse.
I find these are good (not great) quality products with great online reviews. I take them on the odd occasion when I feel I need to.
This is pretty much 'baseline' price where you'll never find them cheaper. Not to mention the range available at Chemist Warehouse is infinitely larger than any at Coles or Woolworths.
I found this as a happy mistake as well online.
it's 50% off all big brands for vitamins actually.
