Chemist warehouse have their Musashi range half price (excluding creatine). They do this every few months so it’s a great time to stock up. Free shipping when you spend over $50.
My personal favourites are the $2kg chocolate protein for $41.99. A mixture of protein bars and the watermelon electrolytes for $13.49 is delish after a big session.
