Just had been to Coles Express for filling petrol and saw that the Asussie Bodies Lo Carb Whip'd protein bar 2 x 30g is for $2.50 (RRP is $4.77)
I have tried almost all the available protein bars out there and by far this is the best tasting one. It has 18g protein per 60g, so not the highest protein to full content ratio, but still worth as a snack.
Thanks for pointing out the protein content. For hardcore people, it should be one of the most important factor
