First post so feel free to roast me.
Everything Musashi is half price at Chemist warehouse, instore and online. Combine with free postage if over $50 for a great deal.
Similar to this expired deal https://www.ozbargain.com.au/node/521425.
No idea when it ends, so get in quick. Obviously a much lower quality than the likes of BulkNutrients but at this price its a no brainer.
Edit: Sale ends 29/10. Thanks to chewkl for the info
Edit2: It appears some stores are still doing the buy 5x bars andget 5% off, or 10x bars and get 10% promo, which stacks with this deal. My local (Abbotsford, VIC) wasn't doing this when I checked.
