I tried these Body Science bars during the $1 promotion at Coles recently, so this price doesn't compare but this might be useful for those who have already run out.
I don't use their protein powder as I use a natural one with less ingredients, but the bars serve me well on the go when I'm desperate.
Grenade Bars are half price but I've never tried them. Keep it Cleaner bars are also half price at $1.75 but I haven't tried them nor can I recommend them.
Available as online only special. Hopefully these specials aren't store specific but I'm uncertain.
